Basically, every time a DRI drawable's clip list changes, the server sets a 
flag in the SAREA to notify the client of this fact.  The client then asks 
the server for the updated clip list via the XF86DRIGetDrawableInfo protocol 
request.

It sounds like either the client is thinking it's getting a bogus clip list, 
or the client and server are getting confused about which buffer is the front 
buffer.
