http://bugs.winehq.org/show_bug.cgi?id=59617 Bug ID: 59617 Summary: wineboot times out and does not copy any system dll (all versions after 10.2, including) Product: Wine Version: 10.2 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: blocker Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: otigkd(a)gmail.com Distribution: --- Created attachment 80678 --> http://bugs.winehq.org/attachment.cgi?id=80678 output of winecfg/wineboot Noticed this last year on all my gentoo machines (the setup on all of them is almost identical: X + Xfce and NO wayland): On a fresh first run either wineboot or winecfg hangs for a rather long time, then fails with the status c0000135 (STATUS_DLL_NOT_FOUND) I have spent a lot of time last year, to find the source of the problem, at first i thought this was a gentoo issue: wine stopped working, when the gentoo ebuilds first got the "X" and "wayland" use flags. An old 10.0 installation still works on my machine, but i would like to update to newer versions, so i decided to find at least the version, that broke it on my machine. After checking out wine (vanilla, NOT staging), and building it and trying to run notepad, I have narrowed it down to the 10.2 release: - wine-10.0: works - wine-10.1: works - wine-10.2: does NOT work - wine-10.3: does NOT work - wine-10.6: does NOT work - wine-10.10: does NOT work I also tried to do a diff between the 2 tags, but there a hundreds of commits to try to rebuild and test them individually. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59824] New: Studio One (versions 6 and 7, Windows x64 builds) crashes immediately when attempting to drag any element on the arrangement timeline.
by WineHQ Bugzilla July 16, 2026

July 16, 2026

http://bugs.winehq.org/show_bug.cgi?id=59824 Bug ID: 59824 Summary: Studio One (versions 6 and 7, Windows x64 builds) crashes immediately when attempting to drag any element on the arrangement timeline. Product: Wine Version: 11.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dwmapi Assignee: wine-bugs(a)list.winehq.org Reporter: ilian.imc(a)gmail.com Distribution: --- Created attachment 81094 --> http://bugs.winehq.org/attachment.cgi?id=81094 minidump from crash Studio One (versions 6 and 7, Windows x64 builds) crashes immediately when attempting to drag any element on the arrangement timeline. The crash is caused by Wine's `dcomp.dll` `device_CreateSurface` stub returning a null/invalid surface, which `cclgui.dll` dereferences during drag visual rendering, resulting in an access violation. ## Application Details - **Application:** PreSonus Studio One (versions 6 and 7) - **Executable:** `Studio One.exe` - **Architecture:** 64-bit (Win x64) --- ## Environment - **Wine version:** wine-staging 11.10 - **Distribution:** Debian GNU/Linux 13 (Trixie) - **Kernel:** 7.0.10+deb13-rt-amd64 (RT kernel) - **Desktop:** KDE Plasma 6, Wayland (XWayland) - **GPU:** AMD Radeon Graphics (RADV RENOIR, APU) - **Mesa/RADV:** 25.0.7 - **DXVK:** v2.3.1 --- ## Steps to Reproduce 1. Install Studio One 7 (Windows build) under Wine 2. Copy `UIAnimation.dll` from a Windows installation into the Wine prefix (`drive_c/windows/system32/`) and set as native, builtin. Without it the app displays "This application requires Windows 10 or later" and refuses to start. This is consistent with `cclgui.dll` using WAM COM class presence as a Windows 10 feature detection check at startup. 3. Launch `Studio One.exe` 4. Open any project containing at least one audio clip on the timeline 5. Click and attempt to drag any clip/element on the arrangement timeline **Result:** GUI freezes immediately, access violation occurs, application crashes and writes a minidump. **Expected:** Element moves with the mouse cursor as on Windows. --- ## Root Cause Analysis (Claude was used) ### Crash address and call chain The crash is an **access violation at `0x100000012d`** (unmapped memory). This address is not inside any loaded module. The call chain reconstructed from the minidump stack (thread `0x208`) is entirely within `cclgui.dll`: ``` kernelbase.dll+0x71e6d (UnhandledExceptionFilter) dbghelp.dll+0x4993 (MiniDumpWriteDump) cclgui.dll+0xc4a10 ← top of actual call chain cclgui.dll+0x4a1d48 cclgui.dll+0x523238 cclgui.dll+0x523190 cclgui.dll+0x523170 cclgui.dll+0x5231f8 cclgui.dll+0x5231c8 ← deepest frame user32.dll+0xc0000 (message dispatch — drag event) ``` ### Register state at crash ``` RIP = ntdll.dll+0xec64 (already in exception handler) RDX = 0x0 ← NULL pointer (2nd function argument) RBP = 0x0 ← NULL pointer RDI = 0xffffffffffffffff RSP = 0x1097a8 (Wine signal stack — very low address) ``` `RDX = NULL` at crash time indicates `cclgui.dll` received a null surface pointer as the second argument to a render call, then attempted to call a virtual method through it, jumping to `0x100000000 + vtable_offset_0x12d` — unmapped memory. ### DirectComposition is the root cause The WINEDEBUG log immediately before the crash shows: ``` 0208:fixme:dcomp:device_CreateSurface iface 0x339EF90, width 1, height 816, format 0x57, alpha_mode 0x1, surface 0x10F668 stub! 0208:fixme:dcomp:visual_SetContent iface 0x3230AE20, content 0000000000000000 semi-stub! ← NULL content 0208:fixme:dcomp:visual_SetClip ... stub! 0208:fixme:dcomp:visual_SetEffect ... stub! 0208:fixme:dcomp:device_Commit ... semi-stub! [crash follows] ``` When a drag begins, Studio One calls `IDCompositionDevice::CreateSurface` to create a drag ghost/shadow visual. Because this is a stub that does not return a real surface object, `IDCompositionVisual::SetContent` is subsequently called with `content = NULL`. `cclgui.dll` then passes this null content pointer into its D2D rendering loop, which dereferences it and access-violations. ### Hard import dependency confirmed Attempting to disable dcomp via DllOverrides produces: ``` 020c:err:module:import_dll Library dcomp.dll (which is needed by cclgui.dll) not found 020c:err:module:import_dll Library cclgui.dll (which is needed by Studio One.exe) not found 020c:err:module:loader_init Importing dlls for Studio One.exe failed, status c0000135 ``` `cclgui.dll` has a **hard static import** on `dcomp.dll`. There is no fallback path. ### Additional context - The `DragSourceHelper2_InitializeFromBitmap` stub fires simultaneously, confirming the drag visual creation path - 1609 `d2d_text_renderer_DrawGlyphRun Ignoring options 0x2` messages flood the log during drag, before and after the crash — the D2D text renderer continues to be called even after the exception is caught, until the second fault (`0x80000003`) terminates the app - `AvSetMmThreadCharacteristicsW("Pro Audio")` is also stubbed (always returns `0x12345678`) but this appears to be a timing coincidence — the MMCSS calls occur at startup and on every thread creation, not exclusively on drag - Tested with VST support completely disabled — no change - Tested with `WINEDLLOVERRIDES="d2d1=b"`, `"dwrite=b"`, virtual desktop mode — no change - The bug affects both Studio One 6 and Studio One 7 — not a regression in 7.2.1 - `UIAnimation.dll` (Windows Animation Manager / WAM) and `dcomp.dll` are used together as an integrated animation pipeline — WAM generates animation curves consumed directly by DirectComposition. The two missing implementations are not independent; fixing dcomp in isolation may not be sufficient if WAM animation primitives are also fed into the dcomp visual tree during drag --- ## Relevant Wine debug output ### Captured with `WINEDEBUG=fixme+dcomp,err+seh` ``` 0208:fixme:dcomp:device_CreateSurface iface 000000000339EF90, width 1, height 816, format 0x57, alpha_mode 0x1, surface 000000000010F668 stub! 0208:fixme:dcomp:visual_SetContent iface 000000003230AE20, content 0000000000000000 semi-stub! 0208:fixme:dcomp:visual_SetClip iface 000000003230AE20, rect 000000000010F670 stub! 0208:fixme:dcomp:visual_SetOffsetY iface 000000003230AE20, offset_y 0.000000 stub! 0208:fixme:dcomp:device_CreateEffectGroup iface 000000000339EF90, effect_group 000000003358F3F0 stub! 0208:fixme:dcomp:visual_SetEffect iface 000000003230AE20, effect 0000000000000000 stub! 0208:fixme:dcomp:device_Commit iface 000000000339EF90 semi-stub! 0208:err:seh:user_callback_handler ignoring exception c0000005 0208:err:seh:user_callback_handler ignoring exception 80000003 ``` --- ## Minidump analysis summary - **Exception code:** `0xc0000005` (ACCESS_VIOLATION) - **Exception address:** `0x100000012d` (not in any loaded module) - **Faulting thread:** `0x208` (GUI/render thread) - **Modules loaded:** 155 total, including `cclgui.dll`, `dcomp.dll`, `d2d1.dll`, `dxgi.dll` (DXVK 2.3.1), `winevulkan.dll`, `wineasio64.dll` - **dcomp.dll** is present and loads successfully — the crash is not a missing DLL but a stub returning null --- ## Related - Similar dcomp stub crash in Dorico (resolved by returning fake S_OK from SetContent/SetRoot/Commit): https://gitlab.winehq.org/wine/wine/-/merge_requests/9839 --- ## Attachments - `Studio One_7_2_1_106594_Win x64_20260605_102312691.dmp` — minidump from crash (246KB) --- *Note: `UIAnimation.dll` used in testing is the native Windows 11 24H2 build copied from a Windows installation.* -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 50382] New: Lego Star Wars Saga needs native d3dcompiler_47
by WineHQ Bugzilla July 14, 2026

https://bugs.winehq.org/show_bug.cgi?id=50382 Bug ID: 50382 Summary: Lego Star Wars Saga needs native d3dcompiler_47 Product: Wine Version: 6.0-rc3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d-util Assignee: wine-bugs(a)winehq.org Reporter: j-r(a)online.de Distribution: --- After installing Lego Star Wars Saga (GOG version) into a fresh 32 bit prefix, the game starts up fine including sound and controls, but with the exception of backgrounds and some effects nothing (logo, menu, in game characters etc) is displayed or replaced by grey boxes. winetricks d3dcompiler_47 fixes that problem. (An older App DB report using wine 3.3 mentions the same problem and fixing it by installing d3d9.) There is no console output indicating a problem in that area (recreating the test with wine 3.3 gives plenty of d3dcompiler error messages; perhaps they have been silenced since then?). Since the other d3dcompiler related bugs I checked all seemed to have d3dcompiler error messages I opened this new report, though it very likely still is a duplicate. Please advise which debug channels to turn on to generate a useful log. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
