SUMMARY The taskbar is unusable while the advanced options window of an app is opened. STEPS TO REPRODUCE 1. Select an app from launcher, right click 2. Edit application > Application Tab > Advanced Options OBSERVED RESULT When the advanced options window is opened, you can not use the taskbar. The advanced options window does not even appear on the taskbar, which is another bug. SOFTWARE/OS VERSIONS Operating System: openSUSE Leap 15.2 KDE Plasma Version: 5.18.6 KDE Frameworks Version: 5.71.0 Qt Version: 5.12.7 Kernel Version: 5.3.18-lp152.81-default OS Type: 64-bit
This is been like this for a long time, though i dunno if it is a bug or intended.
Technically it's because this UI is in the form of a modal dialog window, and modal dialog windows disable their parent, and Plasma is listed as the parent. I think we have a bug report for this already though now I can't find it...
Actually I think this should should be an issue in the Properties dialog itself; the Advanced Options window should always list the Properties dialog as the parent.
