--- Comment #2 from Eoin O'Neill <eoinoneill1...@gmail.com> --- I've confirmed the bug; This issue seems to be caused from a frame regeneration optimization and is 100% reproducible when scrubbing between two frames that have the exact same contents. My thought process for fixing this is that we should do it in two stages: 1) Make an exception to regeneration when any layer on the stack is currently in onion skin mode. This requires the least amount of work, but isn't the most optimized. It would be easy to get this ready for 5.0 immediately. 2) When we rewrite the compositing of onion skins to fix the other compositing problems, we will need to address this issue by changing when and how onion skins are composited. This is already something we need to do in order to fix color-space related issues. For part 2, I will probably need to talk to dkazakov to get a better idea of how we should structure the compositing of onion skins to avoid issues like this in the future. Ideally, it would be done in a separate pass but still respect the layer stack's general compositing order. -- You are receiving this mail because: You are watching all bug changes.
