Krita 4.2.9 is very old. Please update to a more recent version of Krita, and use the appimage.
(In reply to Halla Rempt from comment #1) > Krita 4.2.9 is very old. Please update to a more recent version of Krita, > and use the appimage. Thank you for the answer! Can you please provide me a manual of preferable way to upgrade Krita? Actually I prefer to use packages provided with my Linux distribution.. All of them are up to date.
Use the appimage; that's all there's to it. Most Linux distributions lag behind our releases a lot. And if they do not, they use an unpatched version of Qt, or a version of Qt that's too new and buggy.

Note to everyone who added there comments to this bug: you are using an outdated distribution build of Krita. Krita 4.2.9 is no longer maintained, and, in any case, it's Ubuntu's Qt build that causes this issue. Use the official appimage for 5.0.2 instead.
