ATI user here (AMD Radeon HD 6740G2), r2754 immediately broke games for me.
Tested Dissidia Duodecim 012 and fullscreen option resulted in the screen being cut into 4 flickering parts, some showing pure black and white and overall glitchy graphics.
Anisotropic filtering & anti-aliasing also broken, 2D graphics did not scale at all to fullscreen.
EDIT: My bad, it's broken in 2752 too, something else is causing it...
