yusufipk 77b26e76be Stop the indicator from swallowing clicks in its corner
WA_TransparentForMouseEvents does nothing for a top-level window: Qt
takes the click and then drops it, so it still never reaches whatever is
underneath. Since the window stays mapped while idle, that turned its
corner of the screen into a dead zone for good. Qt::WindowTransparentForInput
is the one that leaves the window without an input region at all.

The dismissable one has to keep taking clicks, and the flag is read once
when the window is created, so it shrinks to a point while concealed
instead. Resizing keeps the surface alive, which is the whole reason
concealing does not simply hide it.

to be a real repaint, not just zero opacity: with the animation stopped
nothing else damages the surface, and the stale frame would sit on the
screen until some other event made the compositor redraw it.
A window that stays mapped also stays clickable, though, and the one
that can be dismissed is the one that takes clicks. Left at full size it
would turn its corner of the screen into a dead zone long after there
was anything to see there, so it shrinks to a point. Resizing keeps the
