[Bug 58143] New: Variable refresh rate does not work properly with winewayland.
by WineHQ Bugzilla Jan. 23, 2026

Jan. 23, 2026

http://bugs.winehq.org/show_bug.cgi?id=58143 Bug ID: 58143 Summary: Variable refresh rate does not work properly with winewayland. Product: Wine Version: 10.6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winewayland Assignee: wine-bugs(a)winehq.org Reporter: jogamer1(a)protonmail.com Distribution: --- When using Wine's wayland backend, variable refresh rate is not working properly according to the monitor's built in refresh rate counter. It works fine on xwayland. Steps to reproduce: 1. Have a monitor and GPU that supports VRR 2. Set up a framerate limiter such as Mangohud, cap the game to a framerate within the monitor's VRR range (most 1080p 144hz monitors with VRR/Freesync/G-Sync have a range of 144hz to 48hz). 3. Launch a game in native wayland mode with 'MANGOHUD=1 DISPLAY= wine game.exe' (assuming dxvk is set up and your GPU supports Vulkan), make sure the game is in fullscreen. 4. Cap the game's framerate, if your monitor has a refresh rate on-screen display watch it spike from the framerate you capped it at to the monitor's max refresh rate. 5. Test it again with xwayland wine in fullscreen 'MANGOHUD=1 wine game.exe', cap the framerate and actiavte the monitor's refresh rate on-screen display. It will stay at/around the game's capped framerate. Using KWin Wayland 6.3.4, Kernel 6.14 Mesa 25.0.3, AMDGPU RX 6000 graphics with a 144hz monitor connected via Display Port. Most Unity engine games launch fine in wayland mode for games to test. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58158] New: Regression: Sacred Gold 2.28 ASE crashes when initialising multiplayer

http://bugs.winehq.org/show_bug.cgi?id=58158 Bug ID: 58158 Summary: Regression: Sacred Gold 2.28 ASE crashes when initialising multiplayer Product: Wine Version: 7.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: zergling.man42(a)gmail.com Distribution: --- Created attachment 78442 --> http://bugs.winehq.org/attachment.cgi?id=78442 git diff 3aa18cc5d01028bda126624ba5f5bfb11ebc4f77 8714eb2fef7182a9c73b9963493935decca89fdc Can be triggered by running Sacred.exe and navigating multiplayer -> any of the three options (local network, closed internet, open internet), or by running GameServer.exe. Causes an unhandled page fault on read access, probably in tincat2.dll. After two bisects, I believe it's caused by 3aa18cc5d01028bda126624ba5f5bfb11ebc4f77, but reverting it doesn't fix it. It's definitely somewhere between 7.2 and 7.3. -- 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 56378] New: Microsoft Edge and Edge-based WebView2 do not function without --no-sandbox option
by WineHQ Bugzilla Jan. 23, 2026

Steps to reproduce: 1. Download and install WebView2 (which includes Edge) from https://developer.microsoft.com/en-us/microsoft-edge/webview2/ 2. Run: wine "/PATH/TO/PREFIX/drive_c/Program Files (x86)/Microsoft/EdgeCore/VERSIONNUMBER/msedge.exe" --disable-gpu --no-first-run Edge will not launch. If you add --no-sandbox to the launch options, it will launch, but freeze after a second or so (https://bugs.winehq.org/show_bug.cgi?id=56377) --disable-gpu is required wine wined3d, it can be dropped if using DXVK. --no-first-run disables the first run prompting you to sign in and such, it has no bearing on this bug itself. This also affects applications using WebView2, e.g. the Adobe Creative Cloud setup application: WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--disable-gpu" wine '/PATH/TO/Creative_Cloud_Set-Up.exe' Using this at least allows the window to open, though it is blank for reasons currently unknown: WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--disable-gpu --no-sandbox" wine '/PATH/TO/Creative_Cloud_Set-Up.exe' -- Do not reply to this email, post in Bugzilla using the above URL to reply.

This is not handled in wine, which calls wcslen on it: https://github.com/wine-mirror/wine/blob/a8c1d5c108fc57e4d78e9db126f395c890… The path resolution is correctly implemented in LdrGetDllPath, but that function is not used (besides being an export).
