Apparently I missed a lot of bug mail last autumn. All your backtraces are in Qt's xcb implementation. There are two sides to this: the first is that Qt has rewritten its xcb implementation for Qt 5.12, and the second Ubuntu might have problems with some library versions. The backtraces don't show a problem in Krita's code. I run Kubuntu 18.04 on my Wacom Mobile Studio, which pretty much similar to running a cintiq attached to a linux computer, and I don't get these problems. We currently have appimage builds of Krita 4.2 pre-alpha, with Qt 5.12, which means you could give those a try and check whether this works better on your system: https://binary-factory.kde.org/job/Krita_Nightly_Appimage_Build/ -- You are receiving this mail because: You are watching all bug changes.
