commit 396dd814 upstream. On many (all?) the Gemini Lake systems we work with, there is frequent momentary graphical corruption at the top of the screen, and it seems that disabling framebuffer compression can avoid this. The ticket was reported 6 months ago and has already affected a multitude of users, without any real progress being made. So, lets disable framebuffer compression on GeminiLake until a solution is found.
