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

On my DELL screen, when switching between app screens, the screen brightness jumps high for a very short period of time (1 second); the screen brightness then returns to normal but it is annoying to have my monitor brightness jump every time I move between app screens.

Steps to reproduce

Open Monitor control
Move between app screens (full screens)

Expected behavior

Monitor brightness to not jump

Anything else?

Yeap, I have a similar issue. When I switch tabs in Chrome, the brightness goes to max and doesn't back to normal.

The brief change happens when you are using software dimming and disable gamma table manipulation. In this case MC uses a dark overlay to dim the screen, however this overlay is not present when there is a transition among desktops. This is normal behavior in this case.

I have a Philips monitor (272E2FA/00). In my case, the screen brightness suddenly goes to the maximum and stays. I noticed this issue is not related to the application. It was fixed when I turned off SmartContrast in the monitor settings.
