> Yikes, this regression made it into a stable release.
I was actually able to reproduce this with 3.14. I tried to reproduce
this before with drm-intel-nightly on SNB, IVB and HSW, but failed.
Turns out I needed a more recent xorg intel driver to uncover the bug. I
bisected the first appearance of the bug to

sna: Enable kernel rotation support by default
but oddly, after
commit b6eeb7a1f7efa591504070b606be655e27e6e9c2

Disable DRI3 by default
turning the rotation on with xrandr causes a black screen that can be
fixed by vt switching away and back to X.
Anyway, I haven't looked yet into why the support for the Present
extension uncovers the bug, but it seems this bug has been in the kernel
for a while.

Title:
Screen tears on xrandr orientation inverted
Status in X.org xf86-video-intel:
Fix Released
Status in xserver-xorg-video-intel package in Ubuntu:
Confirmed
Bug description:
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.
