[Bug 1716024] Re: Mouse cursor movements are jaggy

[Wolf Rogner]

In 17.10 there is no Xorg by default. 17.10 runs under Wayland.

There was a key combination to switch to magnified display. Setting a
fixed resolution does not change the visuals but the coordinate system
of the mouse. After figuring out about the magnification and resetting
it, the mouse worked fine.

=> Can be closed.

Title:
  Mouse cursor movements are jaggy

Status in mpfr4 package in Ubuntu:
  Invalid

Bug description:
  Ever since the update to 3.1.6 (on 8.9.2017) the mouse jumps around
  the screen and does not follow a smooth trail.

  As this was the only update that is related to position calculation I
  suspect the library to be the cause of this issue.

  A similar issue has been reported under #1716022
