Xorg log

[Vedran Rodic (vrodic)]

The bug doesn't happen if I select OpenGL output in VLC, only XVideo output.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Robert Hönig (indielives010)]

This bug does not happen anymore in xenial, having lxde installed
