Blocks disappearing?

[Rattoota]

Im not sure if its a problem on my end, since i haven't found anyone else talking about this problem i imagine it probably is.

Almost every mod-pack i play on i have the issue of the world becoming invisible or colors being strung across the screen. I've been having this issue mostly with packs that i've been playing most of the time i've had Technic launcher. Its been happening for a few months now and it was only doing it to two of the mod packs i play (Sky Factory 1.6.4 and Hexxit) but recently started doing it to Modern Millenaire (1.7.10). Im not sure if im not updated or something and it has to be fixed within my part but the problem is i don't know how to do that. If anyone could help me figure this out that would be great. I would think it'd be something i added onto it but i didn't add any mods to Hexxit so that can't be it. Typically animals and mobs won't be effected and are still visible. Please help
