3.24: Changing brightness causes browser stutter

I’ve noticed lately that sliding the brightness slider from a desktop browser, causes a noticeable stutter in communication between the PB and browser.

If I were getting ~75 fps, and change the brightness from 25-50%, there’s a visible stall with fps drop to ~40. Thankfully it’s just on the browser side, though it does feel new since updating to 3.24.
