http://bugs.winehq.org/show_bug.cgi?id=60037 --- Comment #12 from MattM <mowerm@gmail.com> --- I encountered this problem in an older Electron app (private company app, sorry I'm unable to post it here). I was able to bisect down to the exact same commit as Gergő Sályi found: b868cd31d6b5. I'm building and testing on Debian 13. I also found that toggling "Allow the window manager to decorate the window" resulted in a swap of broken vs. working in Wine 11.12 vs 11.14. - Wine 11.12 with "Allow the window manager to decorate the window" = On: Correct rendering and mouse position - Wine 11.12 with "Allow the window manager to decorate the window" = Off: Incorrect rendering, mouse position also incorrect - Wine 11.14 with "Allow the window manager to decorate the window" = On: Incorrect rendering, mouse position also incorrect - Wine 11.14 with "Allow the window manager to decorate the window" = Off: Correct rendering and mouse position These can be seen in my previous comment's attached screenshot. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
