OR open a window like "Help --> About" OBSERVED RESULT Behind the opened (context) menu / window a darker flashing rectangle appears. Please see the screen recording.i SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20220813 KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Kernel Version: 5.19.0-1-default (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon RX 580 Series
If I do not move the mouse at all, the rectangle flashes in some rhythm: short -- long -- short -- long -- ... If I move the cursor, the flashing becomes much faster.
