[Bug 1799289] [NEW] gucview replaces kde plasmashell display with older one

[Yann Salmon]

Public bug reported:

I started guvcview for the first time since I switched from Xubuntu to
Kubuntu.

guvcview seems to replace the plasmashell display with the appearance it
had when I logged back into my session after resuming from suspend !

The screen capture shows it : the taskbar displays the tasks that were
opened at that time, the notification icons (with activity on the
network icon because it is reconnecting after resuming from suspend) and
of course the time (which if more the 2 hours in the past).

None of these elements are animated (notably not the clock). Clicking on
them does have the usual behaviour, except for tasks where the
"present/actual" task button do not correspond to the display.

Alt-tab also works normally (displaying the actual tasks, including
guvcview).

guvcview seem to work normally, except that the video feed from the
camera sometimes visibly misses a frame. Other application also work.

When I close guvcview, the taskbar is again correctly displayed.

The phenomenon happens each time I open guvcview.
