It's very obvious with the lame xterm+mc test. Which, btw, also flickers in F-15 albeit much faster. Hah! [1] :) Compared with that, when using the most recent F-16 kernel (-> signature) the flickering is twice as slow or even slower. [1] Conclusively, it could be that with my ongoing attempts at converting to gnome-terminal, I have not used mc in xterm in F-15 often enough recently. Nevertheless, in F-16 resizing an xterm+mc window is unbearably slow. -- Fedora release 16 (Verne) - Linux 3.1.0-0.rc4.git0.0.fc16.x86_64 loadavg: 0.20 0.54 0.30 -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
