[Bug 54979] New: Futexes which protect memory allocation congest, causing 100x performance degradation
by WineHQ Bugzilla May 2, 2026

May 2, 2026

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 50778] New: TortoiseMerge closes before showing a window
by WineHQ Bugzilla May 2, 2026

May 2, 2026

https://bugs.winehq.org/show_bug.cgi?id=50778 Bug ID: 50778 Summary: TortoiseMerge closes before showing a window Product: Wine Version: 6.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: lexlexlex(a)gmail.com Distribution: --- Created attachment 69576 --> https://bugs.winehq.org/attachment.cgi?id=69576 Terminal log for TortoiseMerge startup and subsequent closing with wine Steps to reproduce: 1. Install TortoiseSVN in a 64-bit wine prefix. 2. Try to run TortoiseMerge.exe with the wine prefix mentioned in step 1. For example, run "wine TortoiseMerge.exe" from a terminal if the default wine prefix was used. Current behavior: TortoiseMerge closes before showing a window. No TortoiseMerge window appears. Expected behavior: TortoiseMerge is expected to start, allowing the user to compare and merge files in a windowed GUI. Additional information: A download for the current version of the TortoiseSVN installer as of this report is at https://osdn.net/projects/tortoisesvn/storage/1.14.1/Application/TortoiseSV… A log showing terminal output when trying to run "wine TortoiseMerge.exe" is attached. Opinion: This is one of 2 bugs preventing using TortoiseSVN fully in wine. The other is 50756. If these 2 bugs are fixed, TortoiseSVN could be used fully, easing the transition of users whose jobs rely on SVN to Linux. Currently some companies still use SVN and I've tried all the free SVN clients for Linux, and none of them come close to the level of convenience and intuitiveness that TortoiseSVN provides. I have nemo actions ready to enable full usage in of TortoiseSVN in Linux if these 2 bugs are fixed. This would help me personally tremendously, as digging through old revisions in alternate SVN branches is part of my job and extremely difficult with any SVN client other than TortoiseSVN using TortoiseMerge.

[Bug 57852] New: Call from 7BD748A5 to unimplemented function imagehlp.dll.ReBaseImage64, aborting
by WineHQ Bugzilla May 1, 2026

May 1, 2026

https://bugs.winehq.org/show_bug.cgi?id=57852 Bug ID: 57852 Summary: Call from 7BD748A5 to unimplemented function imagehlp.dll.ReBaseImage64, aborting Product: Wine Version: 10.2 Hardware: x86-64 OS: FreeBSD Status: NEW Keywords: download Severity: normal Priority: P2 Component: imagehlp Assignee: wine-bugs(a)winehq.org Reporter: damjan.jov(a)gmail.com I got the Win32 version of OpenOffice (Apache OpenOffice, "AOO") to successfully build on FreeBSD with Wine + Cygwin + Windows SDK, and this was one of the Wine bugs I had to work around during the build. The problem is in the main/postprocess/rebase directory, where it tries to rebase binaries, ultimately calling C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin\rebase (from the Windows SDK), which tries to call the unimplemented function imagehlp.dll.ReBaseImage64, which causes a crash during the build. Since rebasing is just done for better performance, it's not critical and can be worked around by commenting out the relevant makefile command. Still, Wine should ideally support this API, and it's good to document applications that need it. For further details please see the email where I described my experiences, and other Wine bugs I found: https://lists.apache.org/thread/x3p7mv0py2s5hw3cvrm1d3krxgb7cq9k Also if you want to reproduce, you can try compiling OpenOffice on Wine, but it's a very complicated build environment and takes many hours to run, and this bug only happens near the end. See the build guide on https://wiki.openoffice.org/wiki/Documentation/Building_Guide_AOO/Step_by_s… and the extra instructions in the email above. And it is remarkable that Wine works so well, when building a project with ~70000 C++ files, 12 million lines of code, 37 external libraries, code generation during the build, calls to many Cygwin tools and Perl scripts, Java and Ant, .NET tools, and lots more. Only 6 Wine bugs were found, of which 3 are already fixed in Wine 10.2, and the other 3 have workarounds. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59338] New: Menus fail to display after closing child dialog in DAZ Studio 4.24.0.4 (Qt popup recreated but not mapped/shown)
by WineHQ Bugzilla May 1, 2026

http://bugs.winehq.org/show_bug.cgi?id=59338 Bug ID: 59338 Summary: Menus fail to display after closing child dialog in DAZ Studio 4.24.0.4 (Qt popup recreated but not mapped/shown) Product: Wine Version: 11.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: korb(a)qisc.com Distribution: --- Created attachment 80276 --> http://bugs.winehq.org/attachment.cgi?id=80276 Log as detailed in description I was running WINE 11.0-rc4 prior to this week, and it was working fine. The issue started when I updated to 11.0 (I skipped rc5). Steps to reproduce in clean prefix (wineboot --init, no overrides, no env vars): 1. Install base DAZ Studio 4.24.0.4 (no content needed). 2. Launch DAZ. 3. Window → Workspace → Select Layout... → Cancel 4. Try to open Window menu again → menu does not appear (click has no effect). Log (+err,+warn,+qt,+focus,+menu,+popup) shows: - First menu open: system popup created (e.g., 0x10262/0x10264), all standard items inserted (&Restore, &Move, etc.), NtUserThunkedMenuInfo applied, default set, get_menu_state checks. - Dialog close: NtUserDestroyMenu destroys popup handles. - Second (and third) menu attempt: identical creation cycle (new handle, items inserted again, etc.). - But no MapNotify/Expose/visibility events for the second popup — menu never appears on screen. Setup: - Wine: wine-11.1 (apt install --install-recommends winehq-devel) - OS: Linux Mint 21.3 Cinnamon X11 w/ all latest updates applied - GPU: NVIDIA 590.48.01 driver - App: DAZ Studio 4.24.0.4 base install Tested: - Compositing off - Virtual desktop on/off - Qt env vars (QT_X11_NO_MITSHM=1, QT_AUTO_SCREEN_SCALE_FACTOR=0) - Windows version change (10 -> 7) - Focus mode switch (from sloppy to click and back) - No DLL overrides or custom env vars in clean prefix I then ran my test again with WINEDEBUG='+err,+warn,+qt,+focus,+menu,+popup' to produce the attached log. I interjected comments into the log to indicate where I took the actions described above. My comments are on lines that start with "***". -- 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 59028] New: Graphpad Prism 9: project (.pzfx) files cannot be saved if msxml6 is not installed

http://bugs.winehq.org/show_bug.cgi?id=59028 Bug ID: 59028 Summary: Graphpad Prism 9: project (.pzfx) files cannot be saved if msxml6 is not installed Product: Wine Version: 10.19 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: pachoramos1(a)gmail.com Distribution: --- Created attachment 79771 --> http://bugs.winehq.org/attachment.cgi?id=79771 output.txt Hello, I am coming from: https://bugs.winehq.org/show_bug.cgi?id=46568#c10 When I try to run Prism, I cannot save the project file except if I install msxml6 (in that case, I need to run wine-staging as it fixes bug #46568). The error I get looks a bit misleading: a Prism window gets opened saying that "There is not enough memory for normal operations. Please close other programs or exit Graphpad Prism..." I attach the wine command output while reproducing the problem... but I think that errors are not related with this issue (maybe they are more related with a rendering issue with the icons).
