[Bug 54979] New: Futexes which protect memory allocation congest, causing 100x performance degradation
by WineHQ Bugzilla May 3, 2026

May 3, 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 32619] New: Tom Clancy's Rainbow Six: Lockdown can't save a game (directory not created)
by wine-bugs＠winehq.org May 1, 2026

May 1, 2026

http://bugs.winehq.org/show_bug.cgi?id=32619 Bug #: 32619 Summary: Tom Clancy's Rainbow Six: Lockdown can't save a game (directory not created) Product: Wine Version: 1.5.20 Platform: x86 URL: http://www.fileplanet.com/160005/160000/fileinfo/Tom-C lancy%27s-Rainbow-Six:-Lockdown-Demo OS/Version: Linux Status: NEW Keywords: download Severity: minor Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: gyebro69(a)gmail.com Classification: Unclassified Created attachment 43045 --> http://bugs.winehq.org/attachment.cgi?id=43045 terminal output Normally the game should perform an autosave when starting the first mission, and it should allow you to perform a manual save anytime in a mission. Neither of them work in Wine. 1. After performing a manual save in the game, a 'save successful' message is shown on the screen, however, if I open the <Load game> menu, it is empty. 2. When the player dies there is an option to restore the last saved game: clicking on this option results in a crash as can be seen in the attached log file. The demo version doesn't let you save the game, but it does perform an autosave, thus the crash can be reproduced with the demo too. Here's how: 1. install the demo, the game needs native d3dx9_36 and dxdiagn (bug #32163). 2. start the demo with Lockdown.exe, skip the intros. In the menu choose <Single Player> - <Start Mission> and wait until the game is loaded. 3. press '4' to instruct teammates to stay back. There will be some bad guys around the corner, step to them without shooting so the player dies pretty soon. 4. the menu with statistics appears, click on <Load Last Save>...the game crashes at this point. There's nothing serious in the terminal, the game's own log file contains: [ERROR | IkeStateMgr::SaveGame | 735] Could not open file c:/program files/ubisoft/red storm entertainment/rainbow six lockdown demo/data/save/game/autosave.sav This directory structure does exist in Wine: C:/Program Files/Ubisoft/Red Storm Entertainment/Rainbow Six Lockdown Demo/data/save Inside ../save there should be a /game directory which contains the saved games. This directory (as well as an autosave.sav) should be created when you start the first mission. For some reason the /game directory is not created in Wine. Workaround: you have to manually create the /game directory before starting the game the first time. Saving/loading will work from then on. -- 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.
