Timeline Interface locking

I tried this several times and it always locked sooner or later.

When I focus on a piece of the video, and then drag the line marker over it to scan frames to find the frame I want, scanning a bit forward, back, at some point the whole interface locks.
But only the timeline.

It’s impossible to slide left or right, impossible to click the timeline line thing to place it, etc. Gotta restart the program

Sorry but I have never experienced this and will be unable to fix it. Maybe someone else will.

Also I see you ignored the questions requested when posting a bug.

Please try the different options in Settings > Display Method to see if any of them works better on your system.
