Okay, so a few questions:

1. Which version of Krita is this? And which git-hash if possible?
2. Are you building it yourself? It seems that the crash is solely in QT, which might mean that is build incorrectly?
Comment 2 Halla Rempt 2016-06-16 12:39:03 UTC 
Hi Elia,

This is an issue with the combination of Qt, your graphics card and opengl driver. Can you reproduce this with the 3.0 appimages?
