Actually it seems to me that the bug is a bad interaction with light-
locker/lightdm locking system (which relies on vt switch) and the Intel
driver. It only seems to happens on this driver, and I think it's also been
reproduced just by doing vt-switches (but can't remember where it was
reported).

There are at least a gazillion bugs against light-locker and lightdm, or xfce.
I tried to at least merge some of them (like #846278) but clearly failed to
identify all of them.
And people are still reporting new ones (or posting to -devel) so clearly they
are hard to spot.
Maybe locking through vt-switch is a bad idea,
I noted Andreas raised the severity, but I hope someone has an idea how to fix
that because I don't.
