In the video of this issue that I've attached you can see that when I'm using the knobs in the mixer and in the BPM value, the mouse cursor actually moves instead of staying still like it does on Windows and most of the times it escapes the window and goes into the panel, and this behavior can actually break the functionality of some knobs like the BPM one where I literally cannot use it.

[Bug 58578] New: Hygeia Pharmacy: complains that Microsoft ReportViewer is not installed (unimplemented MsiProvideAssemblyW() ?)
by WineHQ Bugzilla May 17, 2026

May 17, 2026

http://bugs.winehq.org/show_bug.cgi?id=58578 Bug ID: 58578 Summary: Hygeia Pharmacy: complains that Microsoft ReportViewer is not installed (unimplemented MsiProvideAssemblyW() ?) Product: Wine Version: 10.12 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: peathot(a)hotmail.com Distribution: --- Created attachment 79093 --> http://bugs.winehq.org/attachment.cgi?id=79093 Terminal output of Hygeia Pharmacy running under Wine Hygeia Pharmacy is a .NET 4 application for pharmacy retail. When the application starts up, it will check for various shared components, ending up complaining that Microsoft Report Viewer has to be installed despite already installed. Attached is the screenshot of the error. It says, "It's necessary to install an additional programed named Microsoft Report Viewer" ("มีความจำเป็นต้องติดตั้งโปรแกรมเสริมที่ชื่อว่า Microsoft Report Viewer"). Terminal output reveals 2 interesting FIXME's: ``` 0174:fixme:msi:MsiProvideAssemblyW L"Microsoft.ReportViewer.Common, Version=10.0 .0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MS IL", L"C:\\Program Files\\HygeiaPharmacy\\HygeiaPharmacy.exe.config", 0, 0, 10D7 A618, 10D7A614 0174:fixme:msi:MsiProvideAssemblyW L"Microsoft.ReportViewer.Common, Version=10.0 .0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MS IL", (null), 0, 0, 10D7A618, 10D7A614 ``` This leads me to believe that the application chokes up because it does not receive the correct path to this .NET assembly, part of MS ReportViewer 2010. --- Looking into multiple documents and into Wine itself, I _think_ it would be relatively simple to implement MsiProvideAssembly[A|W]() using facilities already implemented in Wine. Bug 58577 plays an important role on this. I actually would love to get my hands dirty, if not for 2 problems: 1. I don't actually have much time myself. 2. Many years ago, I disassembled a different component of Windows (related to MDM/management policy) in order to debug my graduating project. I forgot everything by now, and it's IMHO not related, but combined with 1. I think it's probably better to stay safe. (Can I explain some high-level idea? Will I run afoul of 2.?) A number of MSDN documents that might be useful: https://learn.microsoft.com/en-us/windows/win32/api/msi/nf-msi-msiprovideas… https://learn.microsoft.com/en-us/windows/win32/msi/assembly-registry-keys-… Also helpful is a small test program I write myself to exercise MsiProvideAssemblyW() in the same way as the application (and in a slightly different way). On Windows 11, this outputs as follow: ``` MsiProvideAssemblyW("Microsoft.ReportViewer.Common, ..." (qualified)) returns 0 Returned path (119): C:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.Common.dll MsiProvideAssemblyW("Microsoft.ReportViewer.Common" (unqualified)) returns 0 Returned path (119): C:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.Common.dll ``` On Wine, it outputs (excluding Wine's output itself): ``` MsiProvideAssemblyW("Microsoft.ReportViewer.Common, ..." (qualified)) returns 120 MsiProvideAssemblyW("Microsoft.ReportViewer.Common" (unqualified)) returns 120 ``` --- Following is the way I run Hygeia Pharmacy. Hygeia Pharmacy is a relatively complex application and requires the full .NET installation (Mono is not enough). The following commands recreate the environment from scratch: ``` export WINEARCH=win32 export WINEPREFIX=/a/new/prefix winetricks dotnet48 jet40 mdac28 wine ReportViewer.exe # sha256sum: e8ff182e202b321ac2b9245ee20c4eb659008ffb2a34cdbd3486f9da3d4c3e06 wine hygeia_trial_install.2.6.28.1.exe # sha256sum: 380085defb0af240f144d603da70d09a76c940a27a65953a9fbe3668c321b4e2 wine "C:\\\\users\\\\Public\\\\Desktop\\\\Hygeia Pharmacy.lnk" &>hygeia_pharmacy_wine_output.txt ``` --- The (trial) version can be obtained from https://www.hygeia-pharmacy.com/trial/. However, it requires a (free) registration, and the website is entirely in Thai with no English version. In order to (try to) help you with the registration, the registration page at https://www.hygeia-pharmacy.com/register/ requires the followed: 1. A chosen username ("Hygeia ID") 2. A chosen password. 3. Your full name 4. Your email. 5. A math captcha (input the equation's answer). I can't remember if there's an email verification after that step or not, because it's been a long time since I registered myself. Once logged in, https://www.hygeia-pharmacy.com/trial/ will show a big blue button for downloading the trial version. The same page will also be a smaller link for "MS Report Viewer" which is hosted by Hygeia Pharmacy themselves (if you prefer an MS link, see the end of bug 58577). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59519] New: ole32: OLE clipboard caches stale window handle after STA thread terminates, breaking subsequent OleSetClipboard calls
by WineHQ Bugzilla May 17, 2026

May 17, 2026

http://bugs.winehq.org/show_bug.cgi?id=59519 Bug ID: 59519 Summary: ole32: OLE clipboard caches stale window handle after STA thread terminates, breaking subsequent OleSetClipboard calls Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ole32 Assignee: wine-bugs(a)list.winehq.org Reporter: ayourk(a)gmail.com Distribution: --- Created attachment 80543 --> http://bugs.winehq.org/attachment.cgi?id=80543 reproducer source This bug is really starting to bug me ;) so I figured it was time to report it and squash it! I know that in REAL Windows, this works fine, but as you can test from the attached sample app, the clipboard copy only really works once before the application has to be restarted for it to work again. OleSetClipboard fails with CLIPBRD_E_CANT_OPEN (0x800401D0) on the second and all subsequent calls when each call is made from a new STA thread and the main thread has OLE initialized. This pattern is used by .NET WinForms applications. Clipboard.SetText() internally spawns a new STA thread, calls OleSetClipboard, then exits the thread. The main thread keeps OLE initialized (.NET runtime), so OLE_moduleLockCount never drops to 0 and clipbrd_uninitialize() never runs on the copy threads. The cached clipboard window HWND from the first (now-dead) thread is never cleared. This is deterministic, not a race condition. 100% reproducible on Wine 9.0 through 11.0. I even tested it on the latest development branch. The buggy caching pattern has been present since the OLE clipboard was first implemented (commit 557ff419bea, July 18, 1999), so this affects every Wine version ever released. It went unnoticed because the trigger pattern (main thread keeps OLE alive + new STA threads for each clipboard operation) is specific to .NET WinForms applications. Affected application: Space Engineers (Steam App ID 244850) — Ctrl+C works once, then freezes for ~1 second on every subsequent Ctrl+C. The clipboard never updates past the first copy. This is also reported at https://github.com/ValveSoftware/Proton/issues/1792 STEPS TO REPRODUCE ================== Prerequisites: Main thread has OLE initialized (OleInitialize), as in any .NET application. 1. Spawn STA Thread A: OleInitialize(NULL) -> OleSetClipboard(NULL) -> OleSetClipboard(data1) -> OleFlushClipboard() -> OleUninitialize() -> thread exits Wait for Thread A to complete. 2. Paste: OpenClipboard(NULL) -> GetClipboardData(CF_TEXT) -> "first" Result: correct. 3. Spawn STA Thread B: OleInitialize(NULL) -> OleSetClipboard(NULL) Result: returns 0x800401D0 (CLIPBRD_E_CANT_OPEN) All 10 retries fail with the same error. 4. Paste: GetClipboardData(CF_TEXT) -> still "first" Expected: "second" 5. All subsequent copy attempts from new threads fail the same way. EXPECTED BEHAVIOR (Windows) =========================== Each copy succeeds immediately. After step 3, the clipboard contains "second". Tested on Windows 7, 10, and 11 -- all succeed. ACTUAL BEHAVIOR (Wine 9.0 through 11.0) ======================================== First copy succeeds. All subsequent copies fail with CLIPBRD_E_CANT_OPEN. The clipboard permanently retains the first copied text. Each failed copy takes ~1 second (10 retries x 100ms). ROOT CAUSE ========== In dlls/ole32/clipboard.c, get_clipbrd_window() caches a single HWND per process: static inline HRESULT get_clipbrd_window(ole_clipbrd *clipbrd, HWND *wnd) { if ( !clipbrd->window ) clipbrd->window = create_clipbrd_window(); *wnd = clipbrd->window; return *wnd ? S_OK : E_FAIL; } When the STA thread that created this window terminates, the window is destroyed but the stale HWND remains cached. clipbrd_uninitialize() (which clears it) only runs when OLE_moduleLockCount drops to 0, which never happens in a .NET app because the main thread keeps OLE alive. PROPOSED FIX ============ Add an IsWindow() check to get_clipbrd_window(): if ( clipbrd->window && !IsWindow(clipbrd->window) ) clipbrd->window = NULL; This detects the stale handle and forces creation of a fresh window on the current thread. Patch is attached. REPRODUCER ========== A standalone GUI test app is attached (clipboard_test.c + .exe). It has two modes: Mode A (Bug): Replicates the exact .NET OLE clipboard path. - Main thread calls OleInitialize (simulates .NET environment) - Each copy spawns a new STA thread: OleInitialize -> OleSetClipboard(NULL) -> OleSetClipboard(data) -> OleFlushClipboard -> OleUninitialize -> exit - 10-retry loop with 100ms delays (matches .NET Clipboard.SetText exactly) - Three copy/paste cycles with "first", "second", "third" - Copy 1 succeeds; Copy 2 and 3 fail with 0x800401D0 Mode B (Fix): Same OLE operations but manages the clipboard window lifetime correctly, demonstrating the fix works. - All three copies succeed. Build: x86_64-w64-mingw32-gcc -o clipboard_test.exe clipboard_test.c \ -lgdi32 -lole32 -luuid -mwindows Run: wine clipboard_test.exe Log output (clipboard_test.log) is attached showing the failure. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=55518 Bug ID: 55518 Summary: VelbusLink: terminates immediately after creating a window Product: Wine Version: 8.14 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: winehq(a)kazlauskas.me Distribution: --- Created attachment 75080 --> https://bugs.winehq.org/attachment.cgi?id=75080 stdout/err of the failing command When launching the application, the application window will briefly flash and disappear as the application terminates. I made few attempts to catch the moment this happens with `winedbg` to no avail. I’m using wine-staging 8.14 to test it, although I’ve tried various versions including 8.0. To reproduce this issue: 1. Download an installer for VelbusLink: $ curl 'https://www.velleman.eu/downloads/velbus/velbuslink/velbuslink-10.8.6.0.exe' -Lo ~/Downloads/velbuslink-10.8.6.0.exe $ sha256sum ~/Downloads/velbuslink-10.8.6.0.exe 39630e960fe5be289232a6f2409c92ffe0c81e1794f166919aaffddf33eb9814 ~/Downloads/velbuslink-10.8.6.0.exe 2.

Run `wine ~/.wine/drive_c/Program\ Files\ $x86$/Velbus/VelbusLink/VelbusLink.exe`. --- Side notes: * With Wine 8.0 the application fails with an assertion as seen in Bug 50282. In Wine 8.14, there is no assertion failure, but the application fails to launch regardles. * Some version of steam proton manages to run the application, but it is rendered incorrectly with the window frame/background appearing in front of the application contents, making application effectively unusable. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
