gtk_window_is_cut_off

SUMMARY
Once plasma reaches the point of turning off the screen, if I resume the
session, GTK apps apps will not be usable anymore until closed and launched
again, as they become a static picture of their top-left corner put on top of a
black background and don't react to input (see attached picture).

STEPS TO REPRODUCE
1. Launch some GTK app like sublime or evolution.
2. Go away for half an hour so that plasma would lock the screen, then turn it
off automatically (or however the next thing it does is called).
3. Resume the session by pressing some key and re-entering your user password.

OBSERVED RESULT
All or most windows of GTK apps now become static (they have a fixed picture).
The top-left corner of the window will have a snapshot of whatever was there
before the screen got locked, while the rest turns into a black patch. if the
lockscreen showed the music player controls, those will keep being shown over
the black patch at the top-right corner where they would show on the lock
screen. Sometimes, if there are many windows of the same app open, some random
window might survive this and return usable like QT windows do.

EXPECTED RESULT
All apps should resume normally.
