I am having a problem with backing store in PV-WAVE 3.03 under X windows. The
default backing store mechanism is supposed to be that PV-WAVE requests the
server to do the backing store. This is also supposed to be the behavior for
all subsequent windows created after a "DEVICE, RETAIN=1" command. However,
neither of these work for me. I have used two different X windows devices,
both of which I believe are capable of backing store: DECWindows on a
VAXStation 3200 and a Tektronix XN11 terminal (which was set up to have backing
store enabled). DEVICE, RETAIN=2 works, but is quite slow because PV-WAVE itself
makes the backing store.

Has anyone else seen this problem and/or found a fix?
