Ultragear 27GS85Q Pixel grid very visible in some occasions

Really good monitor in my opinion but it has a really big flaw. In some conditions the pixel grid is very visible from a ~50/70cm distance. Sometimes even on desktop. What could it be? I l’ve tried looking for that in my other IPS 1080p 75hz monitor and I can’t see it at all
