Screenshot demonstrating the issue

An apparent redrawing/update issue / regression appeared as I updated to latest
git the intel ddx: When opening a terminal window (urxvt 9.18), parts of the
window sometimes fail to draw or update properly. This is especially apparent
when switching to another virtual desktop and then back again to the one with
the terminal window, the upper half of the window fails to draw.

Sometimes other parts may fail as well. I have not noticed this problem with
any other applications, however.
