[Bug 59148] New: rthdribl performance is worse after ff2f6c4e502c05500e6b9e81066e395f0a1df37d

http://bugs.winehq.org/show_bug.cgi?id=59148 Bug ID: 59148 Summary: rthdribl performance is worse after ff2f6c4e502c05500e6b9e81066e395f0a1df37d Product: Wine Version: 11.0-rc2 Hardware: x86-64 URL: http://www.daionet.gr.jp/~masa/archives/rthdribl_2_0.z ip OS: Linux Status: NEW Keywords: download, regression Severity: normal Priority: P2 Component: opengl Assignee: wine-bugs(a)list.winehq.org Reporter: z.figura12(a)gmail.com CC: rbernon(a)codeweavers.com Regression SHA1: ff2f6c4e502c05500e6b9e81066e395f0a1df37d Distribution: --- This is almost an exact copy of bug 59147, but it's about a different commit. I anticipate the fix will probably look similar, but not quite the same, so I'm filing it as a separate patch. This was found and bisected by Henri. I actually can't reproduce it, but I'm reporting this for Henri since he's out. The crux of the matter is we're doing more GL flushes than we used to, which is not free. Tested with rthdribl, but probably affects pretty much any d3d application. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

by WineHQ Bugzilla Jan. 9, 2026

[Bug 59209] New: Monster Truck Madness 2 takes very long when loading/leaving a race
by WineHQ Bugzilla Jan. 9, 2026

Jan. 9, 2026

http://bugs.winehq.org/show_bug.cgi?id=59209 Bug ID: 59209 Summary: Monster Truck Madness 2 takes very long when loading/leaving a race Product: Wine Version: 11.0-rc4 Hardware: x86-64 URL: https://archive.org/details/MonsterTruckMadness2_1020 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: winehq(a)mrpowergamerbr.com Regression SHA1: 5a8f7d1f745d3fb8fd48d577103ac5068d3c1746 Distribution: ArchLinux In Monster Truck Madness 2, any Wine version after 2f0401c783bb426bc520fcaae18fb2e17fb3318e takes very long to load a race (Driver Check-in -> GO) and it also takes very long to leave a race (ESC -> End Race). At this point in time, the game does not work with the current Wine version (Wine 11.0-rc4, see https://bugs.winehq.org/show_bug.cgi?id=59203) so to reproduce the bug you will need to apply this patch https://bugs.winehq.org/attachment.cgi?id=80102 to make the game actually work. While the other bug has not been fixed, I've decided to already do the work of bisecting the issue to figure out what is causing the bug. To reproduce: * Build Wine 2f0401c783bb426bc520fcaae18fb2e17fb3318e + patch * Build Wine 5a8f7d1f745d3fb8fd48d577103ac5068d3c1746 + patch * Install the game trial version with Wine * Run the game's main executable (Monsterx.EXE) with Wine 2f0401c783bb426bc520fcaae18fb2e17fb3318e + patch, pay attention to how long the game takes to load into a course or when leaving a race * Run the game's main executable (Monsterx.EXE) with Wine 5a8f7d1f745d3fb8fd48d577103ac5068d3c1746 + patch, pay attention to how long the game takes to load into a race or when leaving a race The 2f0401c783bb426bc520fcaae18fb2e17fb3318e version is how the game should take to start/end a race, while 5a8f7d1f745d3fb8fd48d577103ac5068d3c1746 takes a stupidly long time to load and leave a race. This video also demonstrates the issue. The video was made for the bug https://bugs.winehq.org/show_bug.cgi?id=59203, but you can see how the game loaded way quicker on older Wine versions compared to the new version: https://youtu.be/ESd-EBFQu68 While debugging the issue, I found out that removing the entire "if (spec->type == SPEC_WIN16)" block from the `tools/winebuild/spec32.c` fixes the slowdown.

This happens even if you select a subset in the print dialog. Also, there is no "Current Page" option. I suspect this is strictly a dialog issue.

https://bugs.winehq.org/show_bug.cgi?id=46976 Bug ID: 46976 Summary: All games suffer from moderated to severe stuttering with mouse polling ~1000 Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: xinput Assignee: wine-bugs(a)winehq.org Reporter: zeioth(a)hotmail.com Distribution: --- Description: Any game running over Wine will stutter under the next conditions: How to reproduce: * Use a mouse with a polling rate of 1000. * Open any game with wine, using any frametimes measurement tool. * Move the camera quickly in circles.

[Bug 58498] New: OSS driver is triggering Rocket League crash
by WineHQ Bugzilla Jan. 9, 2026

Jan. 9, 2026

http://bugs.winehq.org/show_bug.cgi?id=58498 Bug ID: 58498 Summary: OSS driver is triggering Rocket League crash Product: Wine Version: 10.10 Hardware: x86-64 OS: FreeBSD Status: UNCONFIRMED Severity: normal Priority: P2 Component: wineoss.drv Assignee: wine-bugs(a)winehq.org Reporter: sean-freebsd(a)farley.org This is an odd issue. Rocket League currently has an issue that causes it to crash with a very brief burst of static related to the sound device used. One reported workaround for Windows is to switch from headphones to speakers in settings: https://www.reddit.com/r/RocketLeague/comments/1lflw0s/were_aware_of_a_seas… However, I already have it set to speakers in the game and stereo in winecfg. I tried most configuration of OSS on my system without luck. The only thing that made it run was to change dev.pcm.4.rec.vchanformat from s16le:2.0 to s32le:2.0, however, this causes this game (not others) to produce very distorted sounds. OTOH, I can run the game using ALSA, so that helps push the theory that the OSS driver is reporting something odd to the game or looks like headphones to it. Unfortunately, I have no idea.
