Bug#817195: Same observation

[Michael Hanke <mih@debian.org>]

Hi,

I seem to observe the exact same behavior on a machine with a different
chipset

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

and using a Display Port connection. Gnome shell in use also. It doesn't
depend on the particular DP device connected, and the behavior was
introduced by (or co-occurred with) a recent package upgrade.

If this package is responsible, the most recent upgrade in my system
happened on 2016-03-11, upgrading from 2.99.917-2 to
2.99.917+git20160218-1.

Thanks,

Michael
