SUMMARY STEPS TO REPRODUCE 1. Create a semi-complex animation where frames change from one image to a completely different image/shot (of a different character, image file, ect.) 2. Play the animation using the play button in the timeline OBSERVED RESULT When transitioning from two completely different frames/images, the viewer will lag; even, vertically orientated rectangular chunks of the previous frame will show up on the current frame. The frame will play properly if the animation is paused (not stopped, paused). This bug makes timing complex scenes/transitions rather difficult, and the animation itself is a bit uncomfortable to watch. EXPECTED RESULT The frame should transition instantly and completely from one frame to the next, without feedback/residue (for lack of a better word) from the previous frame. SOFTWARE/OS VERSIONS macOS: 11.6 ADDITIONAL INFORMATION The rest of the 5.0 beta works almost perfectly for animation purposes. =)

It sounds more like an issue with updating the opengl canvas properly. That used to be very slow, but we improved that for 5.1... Though I can reproduce a worse bug on my old macbook pro: when playing the animation with opengl enabled, every frame is black, and stopping the animation and selecting the frame doesn't show anything again.
Is the black canvas not related to bug 459134? I could reproduce that one on the mac mini with M1. As for this report: I cannot reproduce it with the files I've made yet.
I was able to solve my issue by turning off canvas acceleration in settings.
