Hi,

I'll try to reproduce this tomorrow and set to confirmed if I can reproduce it. I've changed the importance to normal. Thank you for your report.

I can confirm this for appimages from 4.3.0 to the Feb 07 5.0.0 prealpha (git 56c1de).

If you first do a paint operation on the mask, such as a small dot in the corner, then copying and pasting it seems to have no problem.

Comment 3 tweetychrip 2021-02-07 22:11:45 UTC

Sometimes the bug happens, and sometimes it doesn't. It's not very consistent.

Comment 4 Vitamorus 2024-12-12 20:03:07 UTC

Reproduced in 4.4.1 but resolved in 5.2.6!

Seems to have been an issue with bounds not being properly set. When there was something drawn on the mask the copy would have trimmed the bounds to contain only was on there. Presumably a blank/white mask resulted in a copy with zero size bounds.
