Having dolphin open causes whole screen to blink every ~3 seconds

[diego_umejuarez_69]

Whenever I even open dolphin, not even run a game, it causes my entire screen to turn black every 3ish seconds. It happens on both dolphin 4 and 5, but does not happen on Faster Melee, which is a modification of dolphin made for super smash brothers melee. Any help would be much appreciated, and I'll be glad to share any more details if necessary. Thanks!
