At certain places, the framerate is fluctuating periodically: about 2 seconds smooth then 3 seconds stuttery, and so on. This is observed and might be limited to Apple Silicon mac.

Research direction
No files, tests, or entry points are named. Start by reproducing the periodic frame-rate fluctuation at the affected places on Apple Silicon using the reported environment, then measure where the timing changes occur. Done means the cause is identified and the alternating smooth and stuttery behavior no longer occurs.
