--- Comment #10 from derp <seria.warty...@icloud.com> ---
hm, are you saying the corruption would trigger for every app where the
application lies about effective opaque region? I think that would make sense,
and there's no way to reasonably protect against that without scanning pixels
every frame.

that btw. reminded me of another app that lies about opaque regions - Telegram
fullscreen viewer of image attachments. it does a direct scanout, but as soon
as you press Meta and open the KDE menu, it starts underlaying other windows in
unused areas. but this one can't be turned into corruption in any way I can
think of, so just a fun fact
