Possible bug. Xemacs screen corruption

Hi. For several months now I've been experiencing screen corruption problems in Xemacs running in X. If I split the main window vertically, and then split one of the sub-windows horizontally, Xemacs doesn't redraw the area in the big buffer next to the bar separating the two smaller buffers. Here's a screenshot: http://www.cds.caltech.edu/~dkogan/corruptxemacs.png I'm currently using Xemacs 21.4.20 on Debian unstable, but the issue has persisted for several months, and isn't limited to the latest version of Xemacs. Has anybody seen this or any thoughts on how to troubleshoot the issue? Remote-displaying an Xemacs session from the affected computer doesn't exhibit the problem. Running on the affected computer shows the problem both with the fglrx and the vesa graphics drivers. It has worked before with some older configuration, but I can't figure out what that was. Thanks. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
