I'm getting bitten by what I think is the copy planes bug in R4.  We
have installed a fix that reportedly fixes the problem, but we are
using R3 clients. Can anyone tell me if the copy_planes bug
is strictly a server phenomena or if it also relates to Xlib &/or
intrinsics.

The fix that I think is pertinant was given in fix-1 as:
	"CopyPlane sometimes mis-fetches source"

When I use our client with the R4 server, I get a complete server
crash (sometimes) when doing a XCopyPlane from a pixmap to pixmap.
Works ok on an R3 server. Doesn't seem to be affected by xset -bc.

I'm getting quite desperate but any work arounds I can think of will
be time consuming and our project is finishing up RSN.

Any help or suggestions will be greatly appreciated.
