 Using Paint activity in os11 in a xo-4, do the following test:

  * draw a few horizontal lines
  * draw vertical lines
  * draw diagonal lines, from one corner to the opposite.

 Result:
  * horizontal and vertical lines are ok, but the diagonal lines show
 jumps, like if horizontal and vertical position are not synchronized.

 You can obtain the touchscreen firmware version in Open Firmware:
