Before opening the issue, have you...?

Searched for existing issues
Looked through the wiki
Updated MonitorControl to the latest version (if applicable)

Describe the bug

Thanks for the great app!
I don't know if it counts as a bug, but the overlay is not only seen by me, but the screen is darkened for people who I share my screen with in zoom meetings and slack huddles.

Is there any chance to hide this overlay from them, and to it only be visible for my eyes only?

Thanks!

Steps to reproduce

Darken the screen using MonitorControl
Start a zoom meeting
On the other side, the screen is also darkened.

Expected behavior

On the other side, the screen should be with it's natural brightness.

Anything else?

No response

@waydabber commented on GitHub (May 31, 2023):

MC should not affect screensharing unless gamma table manipulation is disabled (intentionally or because of a virtual display like SideCar or DisplayLink) and the app falls back to overlay dimming. In this case this is expected.
