Created attachment 104129 [details] Gracsale Color Space — Inversion with Artifacts We have artefacts if we invert image (layer) in grayscale color space.
Sorry, but you have to explain exactly what you do, in words, and what the expected results are and what the problems are. Watching a cursor zip around doesn't tell me enough to start investigating.
(In reply to Boudewijn Rempt from comment #1) > Watching a cursor zip around doesn't tell me enough to start investigating. Sorry!)) My english not is perfect but I will try do it... I just change color space to grayscale and inverts layer twice by pressing 'Ctrl+I'. And you may see artefacts after it. It's not correct. On rgb color space all works fine. :)
