Created attachment 108696 [details] crash report Appveyor version run in the Win10 crashes after some time with big brush sizes (> 500px). There is no specific action besides just doodling around. Crash happens every time, though. And usually after a few minutes of drawing. First time experienced after merging multithreaded-brushes branch. Attaching kritacrash file.
Today's AppVeyor build is at 47d52592, for the record.
Hi, please also download the debug package. The appveyor build should contain a link to the specific version of debugging symbols for the build (the versions must match for it to work). You can follow https://docs.krita.org/Dr._Mingw_debugger to extract the files at the correct location. After that, you can delete your existing kritacrash.log and try to reproduce the crash again, this time there should be more information in kritacrash.log to help debug this issue.
