--- Comment #3 from ratijas <m...@ratijas.tk> ---
IIRC it is an upstream issue with QtQuick not refreshing the texture buffers
after waking up from sleep. Textures would contain a garbage data and need to
be redrawn, but QtQuick doesn't realize that and keeps it cached that way until
the Item source is changed in a way that requires redrawing it.
This is why KWin has "graphical effects have been reset" notification — to fix
the same bug on a window manager level, so that the whole window surfaces and
effect's texture won't stay garbled.
So, probably RESOLVED UPSTREAM, but I'll let KWin wizards say it for sure.
