Bug #329860 (but this is with vt switch, not with external monitors. Might be a seperate problem but symptoms look similar)

possibly https://bugs.freedesktop.org/show_bug.cgi?id=22996


based on these references, and the fact that Felix experiences similar behavior, I'm triaging this this bug accordingly.
