DRC showing Unconnected only when mouse leaves DRC window

[Novak Tamas]

In pcbnew, OpenGL mode, I run DRC, then click on an item of Unconnected tab's list.
Board in the background (below DRC window) is changing only when mouse puts off the DRC window.

This bug together with the missing crosshair cursor (#1606832) makes harder using DRC to eliminate unconnected pins (very short ratsnets lines are hard to spot)

This isn't specific to the "unconnected item" errors. Usual markers also has the same behavior. I think this is caused by canvas only refreshing when mouse moves over it.
