--- Comment #2 from Manga Tengu <mangate...@gmail.com> --- Hi Nick, Definitely not a bug but a perf issue indeed. I must have missed the category (still can't see where it is set up though). I have a few points: - If it can be all toggled at once when in a group layer, maybe it can be even without it? If so, why not improve it as it would mean it's handled in a not optimal way? - 6 10kpx*10kpx layers takes roughly 3 seconds on my machine. (The laptop itself is in good shape and performs very well when I paint or do computing stuff) If I reduce the image to 500*500, things get instant. - I think I remember there are quite some macOS perf issues and artifacts. I believe you will observe it way better on macOS. To name a couple that are still bugging: https://bugs.kde.org/show_bug.cgi?id=434131 and https://bugs.kde.org/show_bug.cgi?id=398689 - Even half a second totally ruins the toggling effect to me. In fact, this really feels long and sluggish when working. Seems our opinions diverge there. -- You are receiving this mail because: You are watching all bug changes.
