I use the activeIcon feature of xterm using these lines in my .Xresources XTerm.VT100.activeIcon: true XTerm.VT100.iconBorderWidth: 2 XTerm.VT100.iconFont: nil2 If I'm running a program which causes a lot of output scrolling (such as emerge -uDNavt world) and iconify xterm, xterm has a chance of locking up. The program becomes unresponsive, and I have to ask FVWM to Destroy it. I've found an easy way to reproduce this problem on my system: run the "yes" command (which dumps out a bunch of "y\ny\n..."), and then minimize xterm. My xterm will lock up right there. (Make sure active icon support is enabled. You may do this using the Ctrl-Middle Click menu and check "Enable Active Icon", or by adding the above XTerm.VT100.* resources to ~/.Xresources, and run "xrdb -merge ~/.Xresources" if your X session scripts don't already do this.)

I see that does use a lot of CPU time. But it doesn't appear to be different from running xterm normally with the same load. On my to-do list I have http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=389476 which reminded me that xterm's not efficiently caching GC's. Improving that would probably fix this as well.
Marking this upstream. Feel free to reopen once there's a patch available at least.
