XL2411Z Help! Overwatch Flickering in Fullscreen

[Graced]

This has really got me confused, when I first set up the monitor using blur reduction and the the 1350 trick this wasn't a problem, but I was having on and off FPS issues where the frame rate would be at 60-90 fps but it would feel choppy (just had this today). I reset the monitor and redid the settings, but when I opened Overwatch the game is now flickering only with blur reduction on, yet it doesn't flicker in a boarderless window.

TLDR: Game is flickering with blur reduction 1350 trick in fullscreen but not in a boarderless window, but is totally fine in fullscreen with motion blur off.
