[Bug 54352] New: Performance tanks when looking at occluded part of the level

https://bugs.winehq.org/show_bug.cgi?id=54352 Bug ID: 54352 Summary: Performance tanks when looking at occluded part of the level Product: Wine Version: 8.0-rc4 Hardware: x86-64 OS: Windows Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d Assignee: wine-bugs(a)winehq.org Reporter: mirh(a)protonmail.ch https://github.com/doitsujin/dxvk/issues/1845 This is basically the equivalent of the missed optimization I had already reported to dxvk (except wined3d had like half the framerate to begin with). With the native nvidia d3d9 driver, you barely can spot a difference in the Mass Effect comm room between looking at the emptiest wall in human history, or the closed door behind that gives access to the rest of the ship. With wined3d, I go from like 220fps to ~70. Btw there's an apitrace in the thread above, if it can help. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Not sure about the crash itself - it's more likely to be graphics related that winegstreamer, but that's just a guess. Anyway, once the crash happens, console is flooded by: 03b0:err:module:DelayLoadFailureHook failed to delay load uxtheme.dll.GetWindowTheme wine: Call from 7B0123C6 to unimplemented function uxtheme.dll.GetWindowTheme, aborting 03b0:err:seh:KiUserCallbackDispatcher ignoring exception and the Unity crash dialog doesn't display properly. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

This is different from the usual broken apps a la "I failed at porting my 32-bit app to 64-bit" (pointer truncation). In this case, pointers from certain allocations are broken into multiple parts and used as indices into multi-level lookup tables. Pitfall: there is a 44-bit user-mode VA limitation (8TB) for 64-bit Windows which was lifted starting with Windows 8.1+. Wine doesn't respect the 44-bit pre-Windows 8.1 virtual address space limits, allowing process heaps to be placed in 0000'7Fxx'0000'0000 range (128 TB) which causes out-of-bounds access to lookup tables when indices overflow (derived from pointer bits). The exception occurs in entry point, causing 'msxml6.dll' to be unloaded. One workaround is to move Wine's top-down allocations/heaps into 8 TB VA range (Wine preloader) and impose same user-mode address space bits limits as with all 64-bit Windows versions < 8.1 to stay "compatible". I've tested it and it works for native here. Not sure if it's worth to change though. I don't know if a separate 64-bit MSXML6 re-distributable package exists that has been fixed wrt Windows 8.1+ address space limits. MSXML6 is part of Windows OS for newer versions and automatically kept up-to-date. $ sha1sum msxml6_x64.msi 1eb84eeae7729ea5db7fe79779f4e216114261ba msxml6_x64.msi $ du -sh msxml6_x64.msi 2.6M msxml6_x64.msi $ wine --version wine-4.0-276-g84459ba94b Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 15039] New: MSVC 6: Menu popdowns too narrow for arrows

http://bugs.winehq.org/show_bug.cgi?id=15039 Summary: MSVC 6: Menu popdowns too narrow for arrows Product: Wine Version: 1.1.1 Platform: PC-x86-64 OS/Version: Linux Status: NEW Severity: minor Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: claus.fischer(a)clausfischer.com CC: claus.fischer(a)clausfischer.com Microsoft Visual C++ 6 is working to a large extent. When opening a menu of the developer studio, the menu items with arrows (that open submenus) are not displayed correctly. The triangular arrows on the right end will stick out of the menu popdown area. I'm not sure if they just stick out to the end of the "shadow" (3d effect) around the popdown, or sometimes more. They should be fully contained in the popdown area. -- 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 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.
