Tested on Pinta 1.2 (reproducing the step from #4 of this thread) on Windows and after step 4 I get new error (never got this error before - see attachment for error message).
But when closing this error message (with X at top-right), selecting "PNG" file type from file type and saving file, it saves without a problem.
