--- Comment #4 from Hoang Duy Tran <hoangduytran1...@gmail.com> --- I was using nightly build (krita-nightly_d2f29d7.dmg), downloaded on 14/11/2021. After read your comment, I went to download the 'krita-5.0.0-beta2.dmg' (today, 18/11/2021) and was able loading all 250 frames, with little delay (sustainable), I still notice the delay when I started playing 'Cache regeneration..' but no 99% stuck as previous version. Still the 'Skip Back' button moves 1 frame backward, identical to the 'Back' button, and 'Skip Forward' button is functioning exactly like the 'Forward' button. I don't understand why you'd need TWO BUTTONS performing exactly the same function. If I was editing I would JUMP by my mouse to a position where I would like to place my next frame, this must be done by MOUSE POINTER, only when I would like to jump to the beginning should I use 'Skip Back' (or rather misleading name, it looks more like 'First Frame' button) and the other looks more like 'Last Frame' button, honestly. -- You are receiving this mail because: You are watching all bug changes.
