Hi Martin, It looks like the issue with Qt 5.12 which we actually fixed in 4.1.7. However, the appimage does not use Qt 5.12, and I've just tested it on my laptop with a built-in wacom digitizer on Ubuntu 18.04 and I don't get a crash like this. Could you also give the Lime ppa a try, and if that also crashes for you, install the debug symbols? See https://launchpad.net/~kritalime/+archive/ubuntu/ppa

I actually thought to have launched the appimage version, but it was the flatpack one. The kde appimage 4.1.7 works fine. Now, hopefully, I've filled the issue in the right bug tracker ;-) https://github.com/flathub/org.kde.krita/issues/12 Thanks!
Thanks for checking!
