Keylight Alt+Eyedropper Hover not updating anymore
Adobe Tech Support didn't understand the problem so I hope someone here does.
I'll do my best to explain it as clearly as possible.

At 6:10 of that video you see him holding down the alt key to find the best shade of green to sample.
The Comp view would update in real time as you hover with alt over the different shades of green.
This always used to work for me, but now it no longer does.
Single clicking the ALT-Key does update the color, but that's a nuisance.
Holding it either won't update, or do so really slowly.
I have tried this with different files (.mov .avi)
I have tried this with different version of AE (2019, 2020)
I have tried this with different view combinations (either Status in Keylight, or Alpha on Comp View)
It almost seems like there is a performance issue, where the eyedropper would sometimes, after I have already released the ALT-key and stopped hovering through the image, keep blinking and stay stuck in the eyedropper tool. Using hotkeys to go to different tools will not work then (selection tool, hand tool, etc).
Hope someone here knows how to fix this.
