I downloaded Pinta from above URL and tested on Ubuntu 22.10. All tests I did it worked fine, no issue anymore.
I also tested on bigger monitor with 2560 x 1440 resolution and created print screen and then <CTRL>+<ALT>+V and I also notice this flickering like maximizing the image and then resize to little bit smaller canvas.
Now we have a decision, should we merge the code or not. In my humble opinion issue in this bug report is a defect of pasting not working correctly and flickering is just an visual imperfection not a defect in the sense of Pinta not working fine.

I suggest to merge the code to the master branch.
