I have been playing Q4 (base) for a while and everything is fine. However, when I upgraded to the 1.4.2 patch, I cannot read the text (i.e. on the loading screen, fps counter & the console). They appear as random white/grey/yellow/red squares. Gameplay is still ok but I cannot read the fps counter and the console. Is there any solution to this? I upgraded from v1.0.0 to 1.4.2.
