           Summary: Fractional scaling causes unwanted mouse acceleration
                    in games

STEPS TO REPRODUCE
1. Set monitor scaling to 125%. Turn off pointer acceleration in plasma
settings.
2. Load CS2 or another FPS game
3. Test for mouse acceleration. I used this method:

OBSERVED RESULT
pointer does not return to starting location with different mouse movement
speeds. Significant mouse acceleration is present unless monitor is set to 100%
scaling.

EXPECTED RESULT
pointer should not exhibit acceleration when using scaling.
