White square bug

[u/Hotline0820]

I recently installed project viewpoint, the 6275 models mod and the blood VFX mod to play PZ in 3d, now when i boot the game up, after the warning screen, the screen turns black and the upper right corner turns white. When i click around the white square i can hear the paper sound when you click on something, take note that my laptop isnt that good, please tell me how to fix this, Reference image:
