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. ============================================================================== Steve Pothier pothiers%tuva.sainet@nmfecc.arpa Science Applications International Tucson, AZ 602-748-7400 ==============================================================================

I'd say the server, but I can't really tell what your bug is.
The fix that I think is pertinant was given in fix-1 as:
"CopyPlane sometimes mis-fetches source"
As far as I know this didn't cause a server crash, it only caused bogus
pixels to appear on the screen.
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.
As usual, we can't diagnose such problems without information. Please
supply a test program or some way of reliably reproducing the problem.
Please extract a stack trace from the server core file. Please tell us
what machine, display, OS, and compiler you are using. Please supply
any other information you think is relevant.mike@tslvax.UUCP (Michael J. Tobias) (03/06/90)
