Brightness constantly changing when in editing screen

[#1]

When im editing my photos the photo will constantly change brightness of the photo (not in any setting of adjustments) unless i go fullscreen or make the screen small. Its not ground breaking but its very irritating to edit go full screen and then back to editing. Its like the photo is self editing brightness or color saturation but no settings change. Please help.

Mac or Windows? Does turning off the GPU help?

Preferences > Performance > set Use Graphics processor to Off.

If it does help, try updating your graphics driver.

I can't see what edits you are making (please learn how to make a proper screen recording and record the entire screen), but it looks like you are using a local adjustment tool (possibly the Adjustment Brush) with mask overlay turned on. When you do not make an edit, the mask overlay is on and it happens to be red, just like the car. When you adjust the sliders of the tool, the mask overlay is temporaily switched off, and so the brightness of the red car is diminished.

Did you ever find a solution? I'm having same issues and can't find anything (well i've tried 100 things i've found, but none are making a change).
