Public bug reported:

Binary package hint: wacom-tools

Using xrandr and xsetwacom to rotate the screen works fine.  Sometime in
the last week or so it started having issues when rotated back to
normal.

Specifically, there are serious display artefacts on the top half of the
screen, and the pen calibration ends up moving the cursor roughly twice
as far as the pen in the horizontal axis, and half as far in the
vertical.

The display artefacts sometimes clear themselves after a couple of
seconds. Other times the screen reverts to black with a cursor.
Switching to a TTY and back to the graphical shell brings it back to
normal in either case.

The pen calibration remains unaffected by subsequent rotations.  The
miscalibration is the same on the physical axes, regardless of the way
the screen is rotated.  Restarting X returns the calibration to normal.
This problem had been occurring previously, but only when the system was
put into standby or hibernate mode.  Most of the reports I remember
seeing listed it as only occurring when the system was suspended while
rotated, however my personal machine would do it if the screen had been
rotated at any point prior to suspend.

Basically, this is very similar to bug 295292, however it is now
happening without the suspend-resume cycle in the middle of it.
