Weird dotted/line patterns on my screen?

I get these weird dotted/line patterns on my screen when I play certain games. They appear when I play Sid Meier's Civilization 5, Minecraft and DayZ. I haven't tested other games for this bug but out of all the games I currently have downloaded, these three games are affected by this bug. They seem to be affected by the Anti-aliasing setting in DayZ and they started appearing after I downloaded Sid Meier's Civilization 5.

I use Steam to play.

No. They are built to absorb the impact
