Short description of error
I get contrasted triangles throughout the interface, everywhere. Ill attach screenshot to understand the issue better. Some materials are also displayed transparent so matter what settings I tweak, and sometimes the model appears to have many black triangles inside it where there is no mesh, inside the empty spaces. I am sure this a graphical issue, but I have tried to install additional drivers and drivers from official sites and ppa's but nothing has worked.
