Public bug reported: When xrandr -o inverted is run, the resulting image is split down the middle. This happens 95% of the time; it has worked once or twice without tearing. Rotation can be activated through unity-control-center Display Settings rotation field, and that reliably works fine. When xrandr -o normal is run, the display returns to normal (although bug #1376760 is observed). xrandr -o right and xrandr -o left also reliably work without issue; this only occurs on xrandr -o inverted. The same behaviors are observed with the longer form of the command xrandr --output eDP1 --rotation inverted, etc.
This has also been reported at https://github.com/pfps/yoga- laptop/issues/28, which uses xrandr commands to invert the display.
