Created attachment 103765 [details] Screenshot of the problem The Favorite section of the blending modes is empty.

Not appimage specific, but the result of a too-eager cleaning up of the kritarc file. Unfortunately, while it was fixed in commit 54ce6c760a055b30426a87fe91316e4b49e80c38 Author: Scott Petrovic <scottpetrovic@gmail.com> Date: Sat Feb 11 12:00:24 2017 -0600 move the favoriteCompositeOps setting to the top. It was previously under the Theme grouping It won't help people who used krita; their local kritarc will have an empty line until they make some composite ops favourite again.
