Sorry I didn't know how to explain it.
Luckily I was able to get a screen shot of it! '>
It just happens when I move around and it happens every couple of seconds but its very quick from when it pops up to when it goes away.
Every couple of seconds or so I start to get these weird map glitches. Where I can see through blocks and it shows me different parts of the underground area for example. It's very quick but very annoying!! How do I fix??? Thank you!!
