[Bug 58511] New: Unimplemented sub function KeAcquireGuardedMutex from ntoskrnl.exe
by WineHQ Bugzilla Feb. 25, 2026

Feb. 25, 2026

http://bugs.winehq.org/show_bug.cgi?id=58511 Bug ID: 58511 Summary: Unimplemented sub function KeAcquireGuardedMutex from ntoskrnl.exe Product: Wine Version: 10.12 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wineserver Assignee: wine-bugs(a)winehq.org Reporter: indigosky30(a)gmail.com Distribution: --- Im trying to figure out why a game that was running a few weeks ago normally doesnt work anymore (gunbound). First, they added Anticheat (SARD), this might be the reason why it fails but trying to debug I found the problem comes from an unimplemented Windows kernel function (note this is an old function introduced in 2003). ------------------------------- 0320:fixme:advapi:DecryptFileW (L"C:\\Program Files (x86)\\GunBoundWC\\game\\sard\\sard_1.0.1.17.sys", 00000000): stub 0320:fixme:ntdll:NtLoadDriver (L"\\Registry\\Machine\\SYSTEM\\CurrentControlSet\\Services\\sard_1.0.1.17"), stub! 0320:fixme:ntdll:NtUnloadDriver (L"\\Registry\\Machine\\SYSTEM\\CurrentControlSet\\Services\\sard_1.0.1.17"), stub! wine: Call from 00006FFFFFC66438 to unimplemented function ntoskrnl.exe.KeAcquireGuardedMutex, aborting wine: Unimplemented function ntoskrnl.exe.KeAcquireGuardedMutex called at address 00006FFFFFC66438 (thread 033c), starting deb ugger... 0350:fixme:dbghelp:elf_search_auxv can't find symbol in module 0350:fixme:dbghelp:elf_search_auxv can't find symbol in module wine: Call from 00006FFFFFC66438 to unimplemented function ntoskrnl.exe.KeAcquireGuardedMutex, aborting 0328:err:service:process_send_command service protocol error - failed to read pipe r = 0 count = 0! ---------------------- Looking at the call inside the ntoskrn routine, KeAcquireGuardedMutex isnt implemented in WINE (not found here) https://source.winehq.org/WineAPI/ntoskrnl.html, but can be found in the Windows kernel (https://gist.github.com/ntddk/56784b8da89f228f5f1d) Im wondering if implementing the function in WINE would solve the problem? Anyhow hoping someone more knowledgeable sheds some light on this problem. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58439] New: REGRESSION: trying to edit a text field immediately causes the previous content to be completely erased
by WineHQ Bugzilla Feb. 25, 2026

Feb. 25, 2026

http://bugs.winehq.org/show_bug.cgi?id=58439 Bug ID: 58439 Summary: REGRESSION: trying to edit a text field immediately causes the previous content to be completely erased Product: Wine Version: 10.9 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: scallegari(a)arces.unibo.it Distribution: --- Hi, I am recently experimenting a regression and even if I cannot say in which version it was introduced, I am almost sure it is not the last one (but before) and that it is indeed a regression (a few month ago the behavior was different). I am working with a software called LTspice (that is closed source but free, which surely helps repro) and available from https://www.analog.com/en/resources/design-tools-and-calculators/ltspice-si…. Incidentally, the developers of this code have traditionally been wine-friendly (even if they do not offer a linux version of their code, neither they provide support for running it in wine, they have tried to ensure that it could be used with wine). This software is a circuit simulator with a schematic capture component. You can pick and place components and edit the values of their parameters using some dialog boxes. Often there are multiple things that can be tuned and the dialog box is arranged as a sort of a table, where some cells are editable. In order to adjust things, until some simulation results are satisfactory, it is common to modify some parameters multiple times and in doing so it is good to be able to edit the previous value. Unfortunately, in recent times it has become impossible to do so when running the software with wine. As soon as you try to modify a value, the value disappears and you remain with an empty field to be filled from scratch. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 57662] New: Cashbooks Complete does not render correctly
by WineHQ Bugzilla Feb. 25, 2026

Feb. 25, 2026

https://bugs.winehq.org/show_bug.cgi?id=57662 Bug ID: 57662 Summary: Cashbooks Complete does not render correctly Product: Wine-staging Version: 10.0-rc5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: winehq.tabloid372(a)passmail.net CC: leslie_alistair(a)hotmail.com, z.figura12(a)gmail.com Distribution: --- The binary is free to download here: https://www.acclaimsoftware.com.au/download/ with no significant depends (access runtime is all). The main window renders using `DISPLAY=:0 wine ..` once a `XWayland&` instance is running otherwise using the native wayland drv backend to `wine-10.0-rc5 (Staging)` results in multiple windows being created that do not show anything. Overall this is a extremely simple program so it is unclear why it doesn't run, I couldn't see anything obvious in the logs. Only a excessive number of `vkd3d:0150:fixme:fold_cast Cast from uint to int2.` prints. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 15346] New: Winamp disappears when you move it's location

http://bugs.winehq.org/show_bug.cgi?id=15346 Summary: Winamp disappears when you move it's location Product: Wine Version: 1.1.5 Platform: All OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: homerhomer(a)gmail.com Created an attachment (id=16178) --> (http://bugs.winehq.org/attachment.cgi?id=16178) DwmSetWindowAttribute error Sort of a silly bug, basically once winamp is up and running, if you click on the title bar and move it around winamp disappears. To make sure that the bug happens make sure to swirl it around a couple of times. ( A Swirly if you will ) Attached I also noticed this when running winamp manually at startup. This may be related. but then I move winamp and it disappears I don't get any more error messages. So I'm not sure. I appreciate the good work Thank you I'm running Ubuntu 8.04, Wine 1.1.5, AMD64 -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email 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 49583] New: Assassin's Creed Odyssey displays black bars on top and bottom.
by WineHQ Bugzilla Feb. 24, 2026

Feb. 24, 2026

https://bugs.winehq.org/show_bug.cgi?id=49583 Bug ID: 49583 Summary: Assassin's Creed Odyssey displays black bars on top and bottom. Product: Wine Version: 5.13 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: GloriousEggroll(a)gmail.com Distribution: --- Created attachment 67739 --> https://bugs.winehq.org/attachment.cgi?id=67739 AC Odyssey black bar fix It's been a long known issue that AC: Odyssey renders with black bars on the top and bottom of the screen (see screenshot 1). Derek Lesho came up with a stub patch that both fixed this -and- allowed STEEP to run (it would not display previously). That patch can be found here: https://github.com/GloriousEggroll/proton-ge-custom/blob/5.12-GE-1/patches/… Recently, the relevant function QueryDisplayConfig was implemented, however it did not contain some of the changes Derek's patch adds. This allowed steep to work, however AC: Odyssey still retained the black bar issue. I modified Derek's patch by adding the relevant parts to QueryDisplayConfig, and removing the relevant flag checks (Derek's patch did this previously), and this allowed AC: Odyssey to render properly without the black bars. (see screenshot 2). The patch is hacky but may provide more information towards fixing this properly. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58325] New: wined3d swapchain use-after-free
by WineHQ Bugzilla Feb. 24, 2026

Feb. 24, 2026

http://bugs.winehq.org/show_bug.cgi?id=58325 Bug ID: 58325 Summary: wined3d swapchain use-after-free Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d Assignee: wine-bugs(a)winehq.org Reporter: yshuiv7(a)gmail.com Distribution: --- Releasing the swapchain brings us to wined3d_swapchain_cleanup, which destroys the front/back buffer textures. Texture destruction is async, happening on the device's command stream. This means these textures can be destroyed way after the swapchain itself. But we did set `texture->swapchain` to `NULL` before queuing their destruction, so that bit is fine. The problem is in texture_resource_unload. Here we try to acquire the context, which goes adapter_gl_acquire_context -> wined3d_context_gl_acquire -> wined3d_context_gl_activate -> wined3d_context_gl_update_window. And here we try to access `context_gl->c.swapchain->win_handle`, which unfortunately points to the swapchain that was just freed. I am unsure what's the fix for this. Do we hold a refcount of the swapchain in the context? Do we clear `context->swapchain` when a swapchain is being freed? Should we release the front/back buffer synchronously? Or something else? -- 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 45882] New: (Overwatch, several source games) Raw Mouse input not working
by wine-bugs＠winehq.org Feb. 24, 2026

Feb. 24, 2026

https://bugs.winehq.org/show_bug.cgi?id=45882 Bug ID: 45882 Summary: (Overwatch, several source games) Raw Mouse input not working Product: Wine Version: 3.16 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: florian98.rg(a)gmail.com Distribution: --- Playing Overwatch I've noticed that the game still uses mouse pointer speed even though on Windows it uses Raw Mouse input exclusively. I've tried this on any branch of Wine (staging, esync, whatsoever) and the problem still persists. This also happens in Valve games where you can enable Raw Mouse Input, e.g. Team Fortress 2 etc. This does not happen with the native ports of said games that use SDL to get mouse input. I already disabled any mouse acceleration in GNOME whatsoever (using the "Flat" Profile), however the problem persists. Is it possible to rewrite Wine to get Mouse input via SDL2 instead? That would help pave way for Wayland etc. Thanks -- 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.
