i recently updated Kinovea, and the playback now freezes / stutters when scrolling through frames. The following video shows the stutter.
I've tried to change memory allocation, and adjust frame rates, but nothing seems to work.
Any ideas?
Thank you

I'm not sure but it might be related to a change in how the videos are loaded specifically in the case of instant replay / observer. Because in this case the goal is normally to load the videos as fast as possible for instant feedback it no longer tries to load the individual frames in memory, as this could cause a big delay. The observer mode tries to stay as lightweight as possible during loading.
See if clicking once on the "reset working zone" button triggers a reload of the working zone into memory. (The blue leftward arrow).
I ended up going to 2024.1.1 - which works better when it works. The problem is that I now face "unhandled exception" errors frequently stating "collection modified".
