Since v11 i've been having this screen glitch whenever a few bricks are builded. When this glitch happens all my screen turns into a bunch of lines. Yes, I did tried the "flushtexturecache;()" script thing, but it doesnt work. I also tryed re-installing BL without bringing back my add-ons, once again, it didn't worked. Heres a few pics of what im talking about.
