I don't get seg faults while resizing, but every once in a while I'll alt-tab to an xterm and start typing, only to have the xterm evaporate. Once it also happened to emacs, which left both emacs and the terminal pretty well unusable. Unfortunately, I don't get a stack trace or any messages in /var/log/XWin.*.log. It just goes away. I'd never seen this behavior with 1.8.2-0 (or earlier), so I'm rolling back to it. I'll holler if the problem continues. Ideas?
