--- Comment #1 from RĂ©mi Bernon rbernon@codeweavers.com --- Could you make a log with WINEDEBUG=+timestamp,+pid,+loaddll,+x11drv,+event,+win ?
FWIW I think UseTakeFocus=Y is better, especially with the window config refactoring, it gives us more control over focus and allows to workaround various broken WM behaviors (see https://gitlab.winehq.org/wine/wine/-/merge_requests/6944).
Proton doesn't use it for historical reasons, and mostly because of WM bugs, hopefully it could change in the future.
