Others have complained of the same issue, with no real consensus on what is causing the behavior.
This most notably happens when there is large area of white on screen, like when working in Adobe Illustrator, Inkscape, Gimp, Excell, etc.
Then, when you move the cursor just off of said thing, the screen darkens, move it back, the screen brightens again, or flickers. The PROBLEM- when the cursor hovers over certain things on screen like icons, buttons in creator applications, brighter or darker areas of the screen(can be just about anything), the screen will slightly, but noticeably brighten or darken, and sometimes flicker back and forth(like its confused about whether to dim or brighten) not a 'glitch' like flicker that you might see with a failing GPU or faulty cable.
