Bug#818519: libqt5core5a: KDE apps randomly switch to unmapped state (hidden)
Package: libqt5core5a
Version: 5.5.1+dfsg-16
Severity: important
Dear Maintainer,
After last upgrade from sid a week ago, several KDE apps randomly switch to "Unmapped" state, becoming invisible even in the task bar.
I can see they are unmapped via xwininfo, the only way to recover i found is with xdotool (or killing them by command line).
Ex.
$ xdotool search --pid `pidof kate`
119538548
119539507
119540209
$ xwininfo -id 119538548 | grep 'Map State'
Map State: IsUnMapped
$ xdotool windowmap --sync 119538548
Note they are not moved to another virtual desktop or activity. I have only 1 activity and 1 virtual desktop, spanning over two screens.
The issues seems to raise when the system get locked for inactivity but i was not able to confirm that every time.
Also I experience that mostly with Kate and Konsole as they are the KDE5 apps i uses more often but i suppose others KDE5 apps would be affected too.
The others always-open app i use is Firefox which seems unaffected (that's why i am guessing the issue is linked to KDE5 only).
