SUMMARY

Krita 4.1.5 instantly crashes on gentoo when doing a Wacom Intuos tablet action, previous version worked really nice.
Other tablet aware applications work nice, e.g. Blender. Also painting with mouse still works.


STEPS TO REPRODUCE
1. Launch Krita
2. Create new file
3. Draw on tablet

OBSERVED RESULT

Instant crash


EXPECTED RESULT

Well not crashing and paining stuff.

Yes... This has been reported umpteen times now. It's because of a bug in qt: https://bugreports.qt.io/browse/QTBUG-72488 . We have a workaround for Qt 5.12, but nobody warned us that Qt 5.11.3 _also_ has the bug. We'll release a new source tarball soon with the workaround valid for 5.11.3 as well.
