Comment 2 for bug 1968045

Dave can you also write what is your Pinta version from Help | About menu. If you installed Pinta from default Ubuntu repository, then you are most probably use Pinta 1.6 that is 6 years old.

It is not a fault of Pinta developers (where you opened a complaint) what version of software is packaged in each of Linux distribution. This is job of particular Ubuntu package maintainer.

But to overcome this problem I suggest to install Pinta from snap package or flatpak package. See: https://www.pinta-project.com/releases/
