        <pre>Yes, it still occurs:

$ uname -a
Linux 4.17.0-rc2

$ glxgears                                                                      
249 frames in 5.0 seconds = 49.732 FPS

Main discussion is here: <a class="bz_bug_link

   title="CLOSED WORKSFORME - Inverted touchpad coasting possibly caused by desktop effects"

To sum up:

It's regression
It occurs since Linux 4.14
It's bisected to dc911f5bd8aacfcf8aabd5c26c88e04c837a938e (drm/i915/edp: Allow
alternate fixed mode for eDP if available.)
It can be fixed either by adding
<a href="https://bugs.freedesktop.org/attachment.cgi?id=135277">https://bugs.freedesktop.org/attachment.cgi?id=135277</a> or reverting bisected
commit.

It's sad that having all of the above doesn't result in any action from
upstream developers for a half year.</pre>
