by WineHQ Bugzilla April 5, 2026

April 5, 2026

http://bugs.winehq.org/show_bug.cgi?id=59624 Bug ID: 59624 Summary: MSFS 2024: RPC_S_SERVER_UNAVAILABLE crash when popping out instrument panels Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: rpc Assignee: wine-bugs(a)list.winehq.org Reporter: akos(a)maroy.hu Distribution: --- Summary Microsoft Flight Simulator 2024 (Steam, AppID 2537590) crashes approximately 77 seconds after popping out an instrument panel (G1000 PFD/MFD) to a second window. The crash originates in rpcrt4.dll with RPC_S_SERVER_UNAVAILABLE. Environment OS: Linux Mint 22 (X11/Cinnamon) CPU: AMD Threadripper PRO 9975WX GPU: NVIDIA RTX 5090 Proton: GE-Proton10-20 with VKD3D-Proton v3.0 built from source (HEAD) MSFS 2024 version: 1.6.34.0 Display: 5120x1440, windowed mode Frame Generation: disabled Reproduction steps * Launch MSFS 2024 via Steam/Proton * Load a flight with a G1000-equipped aircraft (tested: Orbx COWS DA-42) * In the cockpit, hover over the G1000 PFD and trigger panel pop-out (Right Alt + click, or remapped key) * A second window appears and renders correctly for approximately 1 second * After ~77 seconds, MSFS crashes Crash signature 587471.177:0108:012c:warn:seh:virtual_unwind backtrace: 00006FFFFF920CB6: L"rpcrt4.dll" + 0000000000030CB6. 587471.177:0108:012c:warn:seh:virtual_unwind backtrace: 00006FFFFF9102A4: L"rpcrt4.dll" + 00000000000202A4. 587471.177:0108:012c:warn:seh:virtual_unwind backtrace: 00006FFFFF92F2FC: L"rpcrt4.dll" + 000000000003F2FC. 587471.177:0108:012c:warn:seh:virtual_unwind backtrace: 00006FFFFF9136E2: L"rpcrt4.dll" + 00000000000236E2. 587471.177:0108:012c:warn:seh:virtual_unwind backtrace: 00006FFFFF8F529B: L"rpcrt4.dll" + 000000000000529B. 587471.178:0108:012c:trace:seh:dispatch_exception code=6ba (RPC_S_SERVER_UNAVAILABLE) Notes * With older VKD3D (pre-v3.0 git builds as shipped in GE-Proton10-4 through 10-29), the crash was different: a null pointer dereference in the vkd3d-swapchain-sync thread. Building VKD3D-Proton v3.0 from source and injecting it into GE-Proton10-20 eliminated that crash and revealed this underlying rpcrt4 issue. * The pop-out window renders correctly for ~1 second before the hang, suggesting the second swap chain is created successfully but the RPC connection to Xbox Live/gaming services is dropped during or after window creation. * MSFS repeatedly queries rpcss.exe via QueryFullProcessImageNameW in the seconds before the crash, suggesting it is polling for the RPC service which has become unavailable. * The crash does not occur without the pop-out — MSFS runs stably for extended periods otherwise. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59623] New: Dishonored(DE) fails to load built-in (wine) 64bit msvcp90.dll / msvcr90.dll
by WineHQ Bugzilla April 5, 2026

April 5, 2026

http://bugs.winehq.org/show_bug.cgi?id=59623 Bug ID: 59623 Summary: Dishonored(DE) fails to load built-in (wine) 64bit msvcp90.dll / msvcr90.dll Product: Wine Version: 11.6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: msvcp Assignee: wine-bugs(a)list.winehq.org Reporter: ikalvachev(a)gmail.com Distribution: Slackware Created attachment 80688 --> http://bugs.winehq.org/attachment.cgi?id=80688 trace of Dishonored.DE having issue loading built-in msvcp/r90.dll I got the Dishonored (Definitive Edition) game from the Epic Store. From the logs it seems that the game tries to load MSVCP90.DLL, in turn it tries to load MSVCR90.DLL (from winsxs/amd64*) and fails at init. Installing native (win64) libraries with `winetricks` workarounds the problem. Distribution is Slackware64-current. I'm compiling my own wine-11.6 with `--enable-archs=i386,x86_64` aka WoW64. The prefix is about a month old (wine-11.4 at the time). I've run `wineboot -u` to test 11.6. I do have the wine msvcp/r90.dll files in system32 and winsxs/amd64*/ and they are the same as the ones in `wine-11.6/lib/wine/x86_64-windows/` installation. I'm attaching log created with `WINEDEBUG=+timestamp,Dishonored.exe:+module` The log does not contain messages from the EpicLauncher. The relevant part is at the last page. It doesn't look like the problem is unimplemented or missing function/functionality/stub... I don't know what other debug options to use to trace the cause of the problem. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58071] New: Sacred Gold: Crash on startup with specific setup
by WineHQ Bugzilla April 5, 2026

April 5, 2026

https://bugs.winehq.org/show_bug.cgi?id=58071 Bug ID: 58071 Summary: Sacred Gold: Crash on startup with specific setup Product: Wine Version: 10.5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: d3d Assignee: wine-bugs(a)winehq.org Reporter: wine(a)kryotek.mozmail.com Distribution: --- Created attachment 78325 --> https://bugs.winehq.org/attachment.cgi?id=78325 Tar containing the winedbg log and both system's info The game crashes on startup on my desktop PC, but works on my laptop. All the detailed info is in the attachment, here's a TLDR: Game is really old and runs DX7 Both systems are running the latest Arch Linux with KDE Plasma on Wayland, using the zen kernel. Laptop is old, with an integrated Intel i3 GPU and a dedicated NVIDIA 610M. I'm NOT using Nvidia dedicated drivers. Integrated display, it believes an external VGA is connected but that's disabled in KDE. Desktop is a full AMD system with no integrated GPU and a dedicated 6750XT. I have a multi monitor setup with the main being a 1440p 165hz display with VRR, the secondary a 1280x1024 75HZ without VRR. Initially I had the problem using Bottles, but I tried again with a fresh wine installation and a fresh wine prefix and had the same results. I'm using the latest wine 10.5 and manually cloning and building wine didn't fix the problem. The bug is triggered inside "d3d7_EnumZBufferFormats" because the device_iid pointer is 0x438, probably too low to be an actual pointer? If you want help in reproducing and debugging I'm free most of the time and will be happy to help! -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59621] New: "There is not enough video memory to open this frame editor..." error message (in Construct Classic r2)
by WineHQ Bugzilla April 5, 2026

April 5, 2026

http://bugs.winehq.org/show_bug.cgi?id=59621 Bug ID: 59621 Summary: "There is not enough video memory to open this frame editor..." error message (in Construct Classic r2) Product: Wine Version: 11.6 Hardware: x86-64 URL: https://sourceforge.net/projects/construct/files/lates t/download OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: gsw.eugeneulan(a)gmail.com Distribution: Mint Created attachment 80687 --> http://bugs.winehq.org/attachment.cgi?id=80687 Crash log When you try to open/create any Construct Classic's project in Linux Mint 22.3 through the latest Wine, the error message appears that tells: "There is not enough video memory to open this frame editor. Please close some other editors and try again." And after closing it, the program crashes with the log attached in this report. In Kubuntu 25.10 I was not being able to reproduce this crash - any project opens successfully for editing. To reproduce the issue, download the latest ever Construct Classic installer from this direct official link and run the installer in default Wine prefix and follow through all wizard's steps: https://sourceforge.net/projects/construct/files/latest/download SHA-256: 4a37a020a692342e2fbec1a63927a42abefc984b474730227c20311f6e256bfe Ignore the other errors during installation and program's first run, like failed dxwebsetup.exe execution and ID3.csx plugin error - they're happening on Kubuntu for me as well. On firewall prompt you can say No, then create a new project by clicking on File in the top-left corner, select New with any of the two options after it (application / Direct-X game) - then the mentioned error will appear with crash after it. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58966 Bug ID: 58966 Summary: Transparent windows are completely broken under Winewayland driver. Product: Wine Version: 10.18 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winewayland Assignee: wine-bugs(a)list.winehq.org Reporter: cramea(a)proton.me Distribution: --- Created attachment 79670 --> http://bugs.winehq.org/attachment.cgi?id=79670 Comparison image Transparent windows lose transparency and just show up black and also become unclickable and unmovable in WineWayland. Issues are seen in an application called LunaTranslator. I'm guessing any application that uses transparency like this application is broken under WineWayland, but I'm not sure. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 43425] New: 64-bit .NET application crashes with NullReferenceException
by wine-bugs＠winehq.org April 4, 2026

April 4, 2026

https://bugs.winehq.org/show_bug.cgi?id=43425 Bug ID: 43425 Summary: 64-bit .NET application crashes with NullReferenceException Product: Wine Version: 2.12 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: blocker Priority: P2 Component: mscoree Assignee: wine-bugs(a)winehq.org Reporter: tjroamer(a)gmail.com Distribution: --- Created attachment 58791 --> https://bugs.winehq.org/attachment.cgi?id=58791 back trace of the bug I encountered a problem with the 64-bit .NET Framework: My C# program is very simple: Code: static void Main(string[] args) { System.Console.WriteLine("Hello world!"); Debug.WriteLine("Debug Hello world!"); } I installed the WINE-2.12 64-bit on CentOS 7 (3.10.0-514.21.1.el7.x86_64) and installed the .NET Framework 4.6.1 onto it. Before installing the .NET Framework, I removed wine-mono. I got the following error message when I tried to run the above program: Hello world! Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Diagnostics.DiagnosticsConfiguration.Initialize() at System.Diagnostics.DiagnosticsConfiguration.get_IndentSize() at System.Diagnostics.TraceInternal.InitializeSettings() at System.Diagnostics.TraceInternal.WriteLine(String message) at ConsoleApplication3.Program.Main(String[] args) wine: Unhandled page fault on read access to 0x00000000 at address 0x1aa460fd (thread 0009), starting debugger... The problem is with the line "Debug.WriteLine(...)". However, the same application compiled with 32-bit works well. I found out that I got the similar error at other positions when I ran our in-house 64-bit .NET program, even if I don't use Debug.WriteLine(...), so I created the hello-world program to reproduce it. My final goal is: run our 64-bit .NET application on a 64-bit WINE with .NET Framework 4.6.1. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59619] New: Windows with no window control buttons have at least close button
by WineHQ Bugzilla April 4, 2026

April 4, 2026

http://bugs.winehq.org/show_bug.cgi?id=59619 Bug ID: 59619 Summary: Windows with no window control buttons have at least close button Product: Wine Version: 11.6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: gsw.eugeneulan(a)gmail.com Distribution: Mint To replicate this issue, you can launch included executable (HiBitUninstaller-Portable.exe) in the default Wine prefix. The first greeting window "Save Settings" on real Windows doesn't have any window control buttons (minimize, maximize & close). On Cinnamon desktop (tried with Linux Mint 22.3) this window has close button; on KDE Plasma (tried with Kubuntu 25.10) it also has minimize button, but that's another inconsistent behavior regarding window control buttons that has been reported long ago: https://bugs.winehq.org/show_bug.cgi?id=42340 If an option "Allow the window manager to decorate the windows" in winecfg is disabled, then there'll be no window control buttons present, as expected. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
