A fullscreen wine application seems to work correctly, but sometimes when ALT-TAB-ing KDE freezes. Then, killing the application does not help KDE, I need to restart the X server. The problem disappears if I turn off the compositor with ALT+SHIFT+F12.
please provide the output of: qdbus org.kde.KWin /KWin supportInformation please describe the "freeze" situation better. Is the mouse still moving? Can you press alt+Shift+F12? If yes, does that fix the situation?
The mouse still moves. The appearance of the situation varies. Usually the application is half-minimized. Other times the application appears fullscreen and other fully minimized. The application seems to be partially responding to mouse clicks (some sounds clicking certain items), but the screen does not change at all. Pressing alt+Shift+F12 after the freeze does not help. The output of qdbus org.kde.KWin /KWin supportInformation before the freeze (it is impossible after it): KWin Support Information: The following information should be used when requesting support on e.g. http://forum.kde.org. It provides information about the currently running instance, which options are used, what OpenGL driver and which effects are running. Please post the information provided underneath this introductory text to a paste bin service like http://paste.kde.org instead of pasting into support threads. ========================== Version ======= KWin version: 5.7.5 Qt Version: 5.6.2 Qt compile version: 5.6.2 XCB compile version: 1.12 Operation Mode: X11 only Build Options ============= KWIN_BUILD_DECORATIONS: yes KWIN_BUILD_TABBOX: yes KWIN_BUILD_ACTIVITIES: yes HAVE_INPUT: yes HAVE_DRM: yes HAVE_GBM: yes HAVE_X11_XCB: yes HAVE_EPOXY_GLX: yes HAVE_WAYLAND_EGL: yes X11 === Vendor: The X.Org Foundation Vendor Release: 11804000 Protocol Version/Revision: 11/0 SHAPE: yes;

I have upgraded to plasma 5.8.3 and the problem persists.
I observe a similar problem. The problem is reproduced stably. If a wine game is running, (or a native 3d game) is launched in full screen mode. When changing the Alt + Tab window, the kde environment freezes: 1 The taskbar stops showing up-to-date information (does not show the wine game process) 2 The clock on the taskbar does not update, shows the time at the time the game started. It seems that everything in the taskbar stops updating. If there is a crash during the wine game, then exactly what is written in the description of the bug happens. The screen partially stops updating, and mouse movement is not visible. The mouse is visible only with the active window switch in a small rectangle. I guess that the problem is somehow related to the restoration of 3d context. In xfce, this problem does not reproduce. Games to reproduce: 1) kde does not update when alt + tab can be easily checked by installing the game: https://store.steampowered.com/app/203770/Crusader_Kings_II/ 2) the same as in paragraph 1, plus the disappearance of the mouse, and what is written in the description of the bug can be checked by running the game under wine https://london2038.com/quickstart-guide/ This is the first time I'm writing a bug in KDE, correct me if I wrote the wrong way. If you need additional information, I will provide it.
This bug was reported against an outdated version of KWin. We have made many changes since the. If the issue persists in newer versions can you reopen the bug report updating the version number.
