It seems to be in response to a XVidMode requests from the client, so both log
spam and excess X11 traffic. The debug log showed that it only the
Xext/vidmode.c layer and wasn't causing extra work for the hardware (we were
not continuing reprobing the hardware which is what I feared, it's both slow
and any time we touch the hardware there be dragons). From my pov, it is
cosmetic, but it may also be impacting system performance.
