Linux: Weird squares everywhere.

Thanks xsacha. I'll download and test them, then report later.

But I'd really appreciate if you could tell me how to make a build from the source code, I really want to make my own ones for the sake of convenience. All I know is that I need git but from there I don't have a single idea from where to go. I checked the documentation at PPSSPP repository and they seem to give some steps on how to do it but I didn't get any of it.
