krita crashes when using a scrollwheel (or trackpad pinch zoom) on image content

Krita does some weird and wonderful stuff. They seem to rely on being able to get an X11 connection. So I obliged, and this seems to work to some degree in that it now actually shows content and sort of lets me use it. Unfortunately, scroll events crash:

Note that they do also do some funny stuff with QWindowSystemInterface in their codebase, so it could be related somehow, I really don't know. This will need some more digging.
Won't fix. Krita is not going to work with this stuff without work.
