Comment 5 for bug 1921878

Thomas, can you try installing Pinta as snap package and see if it helps.

Benefits of snap package vs. classical deb package is it is run in container isolated from the rest of operating system. So if you install some update of some library on main system or update mono package or similar, you can get in trouble with Pinta deb package, but this has zero effect on Pinta snap package.

You can install Pinta from snap package alongside current Pinta deb package you already have and those two do not interfere (both having its own config files etc). The only restriction is that only one program Pinta snap or Pinta deb can run at one single time.

Installing Pinta from snap:
sudo snap install pinta

Run Pinta from snap:
/snap/bin/pinta

I have been running Pinta snap package for few months without any problems.
