boud is confirming it in the merge request.

Comment 2 Halla Rempt 2022-09-19 11:59:07 UTC

The MR says "The "hangup" is caused by refetching the image when changing display profile. This delay is also present without the patch." -- so that is unavoidable, and there is no reason to keep this report open anymore.
