Created attachment 134200 [details] screenshot with unclickable buttons SUMMARY Under Plasma with wayland I cannot click on buttons in Mysql Workbench app. Given it is a Java app, I assume other Java apps might have problems too. No problems under Gnome wayland. STEPS TO REPRODUCE 1. Open Mysql Workbench 2. Try to click on buttons in the left grey panel to switch between model, mysql connects and migration wizard. OBSERVED RESULT not able to click on buttons EXPECTED RESULT able to click on buttons SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 21.04 KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2
An app not having it's buttons enabled is a bug in the app unless something proves otherwise. Please report there or provide a minimal test case which proves it's kwin
It works under kwin/x11 and under gnome just fine. Problem is only in kwin/wayland
That still all points to a client bug, even if it's one that only triggers under kwin_wyaland. If you attach output of WAYLAND_DEBUG=1 myWorkbenchApp on both kwin and Gnome I will take a glance at the output.
