Bug#840141: Further information

[Alex Dănilă <nuorama@gmail.com>]

One more detail about this bug is that after the freeze the first image 
drawn on the displays is actually a previous "frame" to the one last 
drawn (the one during the freeze).

Unfortunately my video editing skill is too bad to create a relevant 
video in a decent amount of time. I can privately provide a video of the 
whole desktop.

Thank you,
Alex
