Ultrawide displays not rendering correctly
When running at 3440x1440 - Dual 4:3 in Fullscreen or Fullscreen Window, the bottom ~1/5 of the display is just a vertical smear. This doesn't happen at lower (non-native) resolutions in Fullscreen, Fullscreen window, or Window modes.
N.B. The next lowest resolution is not ultrawide (2560x1440)
