http://bugs.winehq.org/show_bug.cgi?id=58671 Bug ID: 58671 Summary: [Damavand] Sonic3D crashes after the main menu + rendering regression Product: Wine Version: 10.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d Assignee: wine-bugs(a)winehq.org Reporter: user.pecheniok(a)gmail.com Distribution: --- Created attachment 79255 --> http://bugs.winehq.org/attachment.cgi?id=79255 Log from a version with correct rendering The first part of the title is pretty self-explanatory, but the second is a bit more interesting. in the first releases of the 10 series, it used to render correctly, but around wine 10.9-10.10 it started rendering solid colors on top of crashing. Not sure if I'll be able to run a bisect, so I'll maybe try to find some prebuilt versions, but 10.0 rc3 had the game rendering correctly, while 9.21 crashed before launching. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59295] New: GOG Galaxy: Maximising the window causes graphical issues
by WineHQ Bugzilla 23 Jan '26

http://bugs.winehq.org/show_bug.cgi?id=59295 Bug ID: 59295 Summary: GOG Galaxy: Maximising the window causes graphical issues Product: Wine Version: 10.19 Hardware: x86-64 URL: https://gogalaxy.com OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: 9427421240(a)posteo.net Distribution: --- When GOG Galaxy is maximised by using the button in the top right corner (or another way to do so), it shows a mix of the content from before maximising the window, a black empty area, and a white border. When maximising the window, this is written to the log: "0120:fixme:dwmapi:DwmExtendFrameIntoClientArea (0001013C, 0022DA90) stub" Before maximising the window, another message is written multiple times to the log: "0254:fixme:dxgi:d3d11_swapchain_Present1 Ignored present parameters 0022F120." This pauses for a while after the window has been maximised. After some time, or when the "Update available"-pop-up appears, some parts of the window can begin to flicker. While the flickering happens, these messages are written multiple times to the log quickly: "0254:fixme:dxgi:wined3d_bind_flags_from_dxgi_usage Unhandled DXGI usage 0x40." "0254:fixme:dxgi:d3d11_swapchain_Present1 Ignored present parameters 0022F130." Occasionally, the flickering can stutter once for less than half a second, and the following message is written to the log: "019c:err:d3d:wined3d_context_gl_set_pixel_format wglSetPixelFormatWINE failed to set pixel format 81 on device context 00000000." One can use the Super-key and then move the window, or hold the Super-key and then open the context-menu (usually by clicking with the right mouse-button), to restore it from the maximised state.

[Bug 58143] New: Variable refresh rate does not work properly with winewayland.
by WineHQ Bugzilla 23 Jan '26

23 Jan '26

http://bugs.winehq.org/show_bug.cgi?id=58143 Bug ID: 58143 Summary: Variable refresh rate does not work properly with winewayland. Product: Wine Version: 10.6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winewayland Assignee: wine-bugs(a)winehq.org Reporter: jogamer1(a)protonmail.com Distribution: --- When using Wine's wayland backend, variable refresh rate is not working properly according to the monitor's built in refresh rate counter. It works fine on xwayland. Steps to reproduce: 1. Have a monitor and GPU that supports VRR 2. Set up a framerate limiter such as Mangohud, cap the game to a framerate within the monitor's VRR range (most 1080p 144hz monitors with VRR/Freesync/G-Sync have a range of 144hz to 48hz). 3. Launch a game in native wayland mode with 'MANGOHUD=1 DISPLAY= wine game.exe' (assuming dxvk is set up and your GPU supports Vulkan), make sure the game is in fullscreen. 4. Cap the game's framerate, if your monitor has a refresh rate on-screen display watch it spike from the framerate you capped it at to the monitor's max refresh rate. 5. Test it again with xwayland wine in fullscreen 'MANGOHUD=1 wine game.exe', cap the framerate and actiavte the monitor's refresh rate on-screen display. It will stay at/around the game's capped framerate. Using KWin Wayland 6.3.4, Kernel 6.14 Mesa 25.0.3, AMDGPU RX 6000 graphics with a 144hz monitor connected via Display Port. Most Unity engine games launch fine in wayland mode for games to test. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58158] New: Regression: Sacred Gold 2.28 ASE crashes when initialising multiplayer
by WineHQ Bugzilla 23 Jan '26

23 Jan '26

http://bugs.winehq.org/show_bug.cgi?id=58158 Bug ID: 58158 Summary: Regression: Sacred Gold 2.28 ASE crashes when initialising multiplayer Product: Wine Version: 7.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: zergling.man42(a)gmail.com Distribution: --- Created attachment 78442 --> http://bugs.winehq.org/attachment.cgi?id=78442 git diff 3aa18cc5d01028bda126624ba5f5bfb11ebc4f77 8714eb2fef7182a9c73b9963493935decca89fdc Can be triggered by running Sacred.exe and navigating multiplayer -> any of the three options (local network, closed internet, open internet), or by running GameServer.exe. Causes an unhandled page fault on read access, probably in tincat2.dll. After two bisects, I believe it's caused by 3aa18cc5d01028bda126624ba5f5bfb11ebc4f77, but reverting it doesn't fix it. It's definitely somewhere between 7.2 and 7.3. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

[Bug 59178] New: Genshin Impact requires ntdll threadpool handling dead workers to not hang on exit
by WineHQ Bugzilla 23 Jan '26

23 Jan '26

http://bugs.winehq.org/show_bug.cgi?id=59178 Bug ID: 59178 Summary: Genshin Impact requires ntdll threadpool handling dead workers to not hang on exit Product: Wine Version: 11.0-rc3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)list.winehq.org Reporter: mkrsym1(a)gmail.com Distribution: --- On exit, the game Genshin Impact calls CloseThreadpoolCleanupGroupMembers from a DllMain receiving DLL_PROCESS_DETACH. At that point all threads except the one that called ExitProcess are already dead, so if there was some callback running on the threadpool when the threads were getting killed, the object will get stuck with num_running_callbacks above 0, therefore cleanup will wait for it forever, and the game process will never exit. If you want to reproduce this in-game (100GB download warning), you will have to disconnect internet for it to start (reasons; not a Wine bug), afterwards you should wait a little for it to submit something on the threadpool and then use the game exit button. About 80% of the time, you are going to hit this specific issue and the game will never terminate, the process getting stuck with 1 thread forever waiting and about 1.2 GB of RAM usage. I have tested this behavior on actual Windows using test programs and am attaching them. Both test programs do not hang on Windows, but hang on Wine. test.c and pool_lib.c: "finished sleep" never gets printed on both Windows and Wine, as the worker thread dies (which confirms that worker threads do indeed die during process exit on Windows too). However on Wine, it later proceeds to hang after "closing threadpool", while on Windows, it terminates normally with "threadpool closed". test_term.c: "callback terminating itself" is printed on both Windows and Wine, same behavior with getting stuck on "closing threadpool" on Wine as above. These test cases show that Windows is somehow able to handle threadpool worker threads dying, and does not get stuck on CloseThreadpoolCleanupGroupMembers afterwards. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
