I have been running some initial tests with two PC X server products:
PC-XSIGHT and TEAMTALK-X ( a repackaged HCl-eXceed Plus ). The client
software I am using is GRAFIT running on an HP 9000/825.

A problem encountered with both products is that if a graphics window
is overlaid ( e.g. by a menu ), the overlaid portion is not restored.
The suppliers of Grafit informed me that the X server implementation
probably did not support backing store  - a requirement for their 
package ( or for the HP Starbase/X implementation? ).

I have just received a third test package - XVISION - and the documents
state that it, too, does not support backing store.

Does anyone know of a PC X server product that supports backing store??
