back-xlib has always flickered a lot here. I'll try to do a bit of
testing, but these things tend to be tricky and timing dependent.

I suspect that the XGetGeometry stuff and the delay in -windowdevice:
are unnecessary now, and that delay might be responsible for this, so
I'd try disabling that code.
