I'm on 20.04 and the steps in #4 did not fix the problem for me.
I open Pinta, then open a 3.4 MB JPG. If I just leave it here, it's fine. Then, I click the rectangle selection tool, starting drawing a selection, it quickly hangs, then crashes. Or I start drawing on the image (the default tool after opening the image is a brush), it quickly hangs, then crashes.
This is even after following the steps in #4 and updating mono to 6.10.0.104.
