Corrupted launcher

Corrupted launcher (black chunks)
Imgur: The most awesome images on the Internet.
So, I've been having some serious problems with the new client since the last three patches or so, I've been quiet with it since I thought it'd finally get fixed, but I'm slowly getting tired of it. The thing is, my whole client gets covered in black chunks, leaving only a few parts visible, and to reveal the rest I have to just click and hover my mouse everywhere around. This wouldn't be an issue if not the fact it also happens during the champion select. Yesterday I completely reinstalled League, wiping all the residual files and performing a clean reinstall, as well as choosing the "Initiate Full Repair" option. Nothing helped, obviously. Some more examples of what's going on: Lastest log: And no, I'm not creating those black rectangles myself in MSPaint {{champion:32}}
