Bisected to: 0b6decb103b01187d7665cc9942687df1f1ff22f is the first bad commit commit 0b6decb103b01187d7665cc9942687df1f1ff22f Author: Xaver Hugl <xaver.hugl@gmail.com> Date: Wed Jan 1 22:26:25 2025 +0100 remove the x11 operation mode, and the x11 standalone backend A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/7623 Git commit ba13665e9ea72da5e52c8d486dc97c9e987498c1 by Vlad Zahorodnii. Committed on 17/05/2025 at 12:49. Pushed by vladz into branch 'master'. Properly unmap minimized and hidden X11 windows Amends 0b6decb103b01187d7665cc9942687df1f1ff22f. This is what kwin used to do prior to the split. Video games probably break because they monitor UnmapNotify events, and with internalKeep() they never arrive.

Committed on 14/10/2025 at 14:14. Pushed by vladz into branch 'Plasma/6.5'. x11: Restore "kept" window state Effectively reverts c8efb221b361a0100e93797383ffa51e963d0166. Video games are susceptible to the kept window state. If a video game is put behind other windows, it will eventually break and it may not recover from the broken state after it is made visible. The likely reason why video games break is due to frame callback starvation. c8efb221b361a0100e93797383ffa51e963d0166 attempted to address that issue by unmapping the windows. However, it made X11 windows flash when switching between virtual desktops or activities using a touchpad. When a window is mapped, Xwayland will immediately destroy and create a new wl_surface. For the time being, this change brings back the old behavior so 6.5 still has the same behavior as 6.4 and we have more time to figure out what to do for 6.6.
