Bug ID: 378532 Summary: fast window switching (ALT+Tab) is broken for fullscreen windows Product: kwin Version: 5.9.4 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: kwin-bugs-n...@kde.org Reporter: plusf...@gmail.com Target Milestone: --- KDE Frameworks 5.32.0 Qt 5.8.0 (built against 5.8.0) The xcb windowing system (also on Wayland) Open a few windows, now you can "fast switch" between 2 windows via ALT+Tab. That works good and many use it. Now when you open a game (Stardew Valles, Tomb Raider, RocketLeague and all other games i have in Steam) and its launched fullscreen, fast user switch will not work anymore. Start the game -> game opens ALT+Tab switches out of the game another ALT+Tab will NOT switch back to the game, but a random other window. It seems this only affects OpenGL and Vulkan windows. If i run Chromium with F11 in fullscreen an can switch just fine in and out. If I start the game in windowed-mode, fastswitch also works fine.
