Hello. Are you able to reproduce this crash with recent 4.4.0 update as well? I tried it on my Pixelbook (Intel). But couldn't reproduce it. The attached crash log isn't related to Krita I'm afraid. If you could attach one by doing `adb logcat --pid=$(adb shell pgrep krita)` -- maybe then I'll have a clue.

Git commit 194bc293b8122f5b0b2cbd8ba20dc8af2b20201f by Sharaf Zaman. Committed on 09/11/2020 at 09:20. Pushed by szaman into branch 'krita/4.3'. Bugfix: crash when File->Quit is used or.. if app is killed. This happens on ChromeOS and few other devices which let the process live a beyond the Activity, so when the control reaches exit() on C++ side -- it crashes while cleaning global static state.
