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

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.
