SUMMARY If one tries to resize/move a window only by using the keyboard, the key strokes are propagated to the active application which runs inside the window. This is a longstanding bug (several years old). STEPS TO REPRODUCE 1. Open Konsole. 2. Move the window only using the keyboard: Alt + F3 > More Actions > Move > Cursor keys up/down/right/left > Enter when satisfied. OBSERVED RESULT If you hit the up or down cursor during the moving process Konsole's history function is invoked. The Enter key to complete the action produces an new blank prompt or executes the command on the prompt. EXPECTED RESULT Key strokes should not be propgated to the application during moving action. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.23 KDE Plasma Version: 5.23.1 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.3 Kernel Version: 5.11.0-38-generic (64-bit) Graphics Platform: X11
I stumbled upon this recently as well, it only happens in X11. Changing X11Client to always grab the keyboard during resize/move (see attached diff), fixes this...but with the undesirable side effect that Qt widgets appear "unfocused" whenever you move/resize a window.
Created attachment 142932 [details] X11Client patch
