[Bug 59018] New: Font artifacts on glyphs with overhangs
by WineHQ Bugzilla 21 Nov '25

21 Nov '25

http://bugs.winehq.org/show_bug.cgi?id=59018 Bug ID: 59018 Summary: Font artifacts on glyphs with overhangs Product: Wine Version: 10.17 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: trivial Priority: P2 Component: win32u Assignee: wine-bugs(a)list.winehq.org Reporter: gamelaster(a)outlook.com Distribution: --- Created attachment 79757 --> http://bugs.winehq.org/attachment.cgi?id=79757 Images of the issue + PoC patch In the game MTA San Andreas (multiplayer modification for GTA San Andreas), in game chat and other parts using relevant API, some glyphs have leftover artifacts (images in attachment). ---------- User vahook from MTA:SA community was so kind that he investigated this issue and found the root cause, with hacky PoC fix provided. Quoting his explanation: >> The DrawText methods in Microsoft's d3dx9 implementation expect the ExtTextOut functions in GDI to opaque overhangs as well (TTF glyphs with a negative abcC value) when invoked with the ETO_OPAQUE option, as DrawText will use abcA + abcB as the glyph width when copying the rasterized glyphs from a (reused) temporary buffer to a texture. However, the current implementation in NtGdiExtTextOutW opaques out an abcA + abcB + abcC wide box, meaning the background behind overhangs won't be cleared, resulting in artifacts in the font texture from previously rasterized glyphs. In the attachment archive, there are images of the bug, also with image of PoC fix applied. PoC Fix patch is there as well. Additionally, there is font texture dump from the game, which shows that the artifacts are present in the texture. Vahook provided reproduction code as well, which I modified a bit to forcefully use d3dx9_42.dll for successful reproduction. The code can be found here: https://github.com/gamelaster/wine-gdi-font-artifact-repro with prebuilt binaries (built by me) available to be downloaded here: https://github.com/gamelaster/wine-gdi-font-artifact-repro/releases/tag/v1.… . -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 54979] New: Futexes which protect memory allocation congest, causing 100x performance degradation
by WineHQ Bugzilla 21 Nov '25

21 Nov '25

https://bugs.winehq.org/show_bug.cgi?id=54979 Bug ID: 54979 Summary: Futexes which protect memory allocation congest, causing 100x performance degradation Product: Wine Version: 8.0.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: nagle(a)animats.com Distribution: --- Created attachment 74518 --> https://bugs.winehq.org/attachment.cgi?id=74518 Debugger output with multiple threads stuck in spinlocks. SUMMARY Under the wrong circumstances, a program doing many memory allocations from multiple threads can experience more than 100x performance degradation. I'm seeing this in my own Rust program, which has 16 sometimes-compute-bound threads on a 12 CPU machine. This works fine on Microsoft Windows and when compiled for Linux. Under Wine, it can be over 100x slower. Multiple threads are banging on a spinlock at _InterlockedCompareExchange [Z:\usr\src\packages\BUILD\include\winnt.h:6630] in ntdll spin_lock [Z:\usr\src\packages\BUILD\dlls\ntdll\sync.c:937] in ntdll This is the spin lock around the queue for pausing threads. DISCUSSION This looks like futex congestion. That's a known kind of problem, but doesn't seem to have been seen in Wine before. It may be that some programs just run really slow under Wine, and nobody knows why. The code in NTDLL is clearly intended to handle the fast case without doing an OS-level lock. Under light load, that's O(1). But under heavy load, with multiple threads pounding on spinlocks, each spinlock waits longer, and there are multiple threads, so it becomes O(N^2). Which means huge slowdowns. See discussion at https://forum.winehq.org/viewtopic.php?t=37688 which has snippets of the code that's causing the problem. I can copy all that info over here if necessary. Let me know. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 54455] New: CodeMeterRuntime: Install fails with '00c4:err:service:process_send_command service protocol error - failed to write pipe!'
by WineHQ Bugzilla 20 Nov '25

https://bugs.winehq.org/show_bug.cgi?id=54455 Bug ID: 54455 Summary: CodeMeterRuntime: Install fails with '00c4:err:service:process_send_command service protocol error - failed to write pipe!' Product: Wine Version: 8.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: irmin.okic(a)gmail.com Distribution: --- Created attachment 74012 --> https://bugs.winehq.org/attachment.cgi?id=74012 Terminal output of the installer. Steps to reproduce: * Install dotnet48 into the prefix with winetricks. * Download CodeMeterRuntime 64bit 7.60 (but earlier versions had the same error) for Windows from: https://www.wibu.com/us/support/user/downloads-user-software.html * Execute the installer. * To reduce complexity in the installer on the Custom Setup step select "don't install" for all components except "CodeMeter Runtime Kit". I.e. "don't install" for Network Server, WibuShellExtension, User Help, Automatic server search, Remote access to WebAdmin. * Finish the installation. The installer will state that it ended prematurely. The relevant errors are probably: 00c4:err:service:process_send_command service protocol error - failed to write pipe! 016c:err:msi:ITERATE_StartService failed to start service L"CmWebAdmin.exe" (1053) 016c:err:msi:execute_script Execution of script 0 halted; action L"StartServices" returned 1627 016c:err:msi:ITERATE_Actions Execution halted, action L"InstallExecute" returned 1627 In Wine 7 I ignored the installer error with the following arguments to the installer: /ComponentArgs "*":"/qn ADDLOCAL=Complete,DotNET_Modules,AutomaticServerSearch REMOVE=WibuShellExtension,EnableNetworkServer,AccessToWebAdmin /l*v C:\users\z0rb\Temp\keyinst.log /norestart DISABLEROLLBACK=1 PROP_CMCC=\"none\"" The important argument was DISABLEROLLBACK=1. This meant that I can keep the install even with the failure. Then run CodeMeterCC.exe which started the CodeMeter windows service. With that service I could use further software that uses CodeMeter as their licensing service. In wine 8 even that service (together with CmWebAdmin.exe) started having the "failed to write pipe error!". I am out of workarounds at the moment and asking here for help. If you can instruct me with further debug flags and similar to narrow down the error I am ready to put in the work. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
