--- Comment #6 from Adam Bolte abolte@systemsaviour.com --- I'm seeing this too. Running a BenQ XL2730Z (2560x1440@144Hz) gaming monitor, but some games (eg. Prototype 2 under Wine, Saints Row 2) only accept resolutions up to 1920x1080. They cause GPU scaling to automatically kick in (the monitor reports the resolution is still 2560x1440) and everything looks too horrible to look at.
Fury X, Mesa 17.0.1.
If I run the scaling mode with Center instead of Full aspect, everything looks great (but annoyingly small).
