When I zoom in on the timeline the application starts freezing and I see the spinning wheel cursor for a couple of seconds. If I try to do anything while zoomed in it freezes again and again until I zoom out.

STEPS TO REPRODUCE
1. Open a project
2. Zoom in as far as possible om the timeline

OBSERVED RESULT
Application freezes for a couple of seconds

EXPECTED RESULT
It should perform equal regardless of zoom level of the timeline.

There have been work on improving the way audiothumbs get drawn in timeline which caused this issue. Can you please test and let us know if it still happens.
