Hornedreaper - Bright screen while alt tabbed

Hi there, im having the same problem but from what ive notice. Its nvidia experience whos causing crashes. As a check just switch it off and try alt tab then. If so and you dont need it get rid off it. Hope that helps.

Hey there,

The most common cause for this are applications that dim the screen, such as:

  • f.lux
  • Windows nightlight
  • Other programs that control screen brightness

These do not work with full screen applications and will be temporarily disabled while Starcraft 2 is running in full screen mode. The most common fix is to switch to Windowed Borderless which visually is similar to Full Screen mode but has some differences in the back-end of the system.
