--- Comment #5 from moritz1...@googlemail.com --- (In reply to Nate Graham from comment #4) > Can you do this: > 1. Restart kwin with `kwin_x11 --replace` in a terminal window > 2. In another terminal window, run `qdbus org.kde.kglobalaccel > /component/kwin invokeShortcut "ExposeAll` > 3. Go back to the first terminal window and see the text output; post it here Hello Nathan, `kwin_x11 --replace` helped me a lot. The output was: >kwin_x11 --replace > > ✔ >kwin_xkbcommon: XKB: inet:323:58: unrecognized keysym "XF86EmojiPicker" >kwin_xkbcommon: XKB: inet:324:58: unrecognized keysym "XF86Dictate" >qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 2109, resource >id: 106954788, major code: 3 (GetWindowAttributes), minor code: 0 >qt.qpa.xcb: QXcbConnection: XCB error: 9 (BadDrawable), sequence: 2110, >resource id: 106954788, major code: 14 (GetGeometry), minor code: 0 >qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 2121, resource >id: 106954792, major code: 3 (GetWindowAttributes), minor code: 0 >qt.qpa.xcb: QXcbConnection: XCB error: 9 (BadDrawable), sequence: 2122, >resource id: 106954792, major code: 14 (GetGeometry), minor code: 0 >kwin_platform_x11_standalone: Compositing disabled: video driver seems >unstable.

I guess my issue is solved for now although I still don't know why it happened in the first place. -- You are receiving this mail because: You are watching all bug changes.
