odd multi coloured bug

slifin

I was in the area behind the crashed ship's engine where there is a lot of salt and scrap, I appeared to clip with the ground a little bit then I started seeing all these colours
until it took over the entire screen
the picture is taken from when I paniced and took a screenshot as I swam up to my sub

Phalaguim

Oh wow, that's bad. Installed latest drivers? Clean video card/cpu fan.. pc/lappy overheating?
