Video showing the monitor becoming bright when a window touches my floating
dock causing it to touchdown against the border betwee the screens
DESCRIPTION
I have an SDR screen and two HDR screens. Whenever I move my mouse between the
SDR screen and the first HDR screen while my dock is touching the border
between the two screens, the SDR screen becomes really bright as if the gamma
got turned way up or it's trying to be HDR maybe?
This only happens if all 3 screens are enabled and the SDR screen is set to
efficiency mode.
If something happens on the SDR screen (like a notification) or I just wait a
while, it goes back to normal.
If I set the dock to floating, it fixes it because the dock is not touching the
border.
STEPS TO REPRODUCE
1. enable 3 screens, 1st (left) SDR
2. set the SDR screen to efficiency mode
3. make a dock on the 2nd screen that touches the border between the 1st and
2nd screen
4. move mouse between the two screens
OBSERVED RESULT
SDR screen becomes bright (gamma) as if it thinks it's HDR or something
EXPECTED RESULT
Screen should not change brightness/gamma
