Yes, the problem occurs only on that resolution and on fullscreen and stays even with level transition. After tinkering I figured out that:
-If the input on my monitor is DVI, I have NO problems AT ALL, even when I don’t have other cables plugged in(like an HDMI cable)
-If the input on my monitor is HDMI AND I have another cable plugged in my monitor (works both with HDMI and DVI cables), I have NO problems AT ALL
-If the input on my monitor is HDMI AND there is NO other cable plugged in my monitor, the problem happens
