Messed up output picture

Been using SNA on intel SNB hardware for a while now and and just updated to 2.21.5. Seems like the output gets messed up when I log in to GNOME and it changes the xrandr configuration. Switching to UXA works around it.

The framebuffer seems to be fine since taking a screenshot yields a perfectly normal looking desktop but what actually gets sent to the monitor is different, see the attached pic.

Not a bug in SNA at all, even UXA is susceptible...
