This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 3 Ben Skeggs 2012-12-19 22:10:13 UTC
Are you able to give more information on the exact setup you used?  I was unable to reproduce the issue on a Quadro 400 on either DVI or native DP connection.

Comment 4 Tomas Pelka 2013-01-04 10:48:40 UTC
Ben what do you mean by exact setup?

I mean: What type of display do you have connected to each connector, what adaptors are in use, etc etc.
