Public bug reported:

After changing from a lower resolution to 4k bottom left of the screen
looks fine everything else flickers. When I restart X11 the whole screen
looks perfect.

Seems like a problem with mode setting and/or MST?

I am using a lenovo thinkpad T440s with a dockingstation (but also seems
to happen when not connection through the docking station).
