Public bug reported:
after doing xrandr --output HDMI2 --scale wxh, using any values except
1x1, the screen becomes increasingly distorted when typing in an editor
window. The problem first appears as images of the previous cursor
position being left behind, but as typing continues, lines below that
being edited become increasingly garbled. The distortion can be removed
temporarily by dragging the window to a different position. But of
course it comes back as soon as editing resumes. The problem appears
also in typing in an xterm window, as the image of the cursor gets left
behind while typing the space bar. This makes the scale option
completely useless for my usual purposes, and forces me to live with a
screen resolution that doesn't properly fill the external monitor. The
problem did not exist in xrandr 1.3.3 on my old system.
