With kernels 2.6.38 or 2.6.39 xterm and rxvt do not update the content properly. E.g. I enter "ps -ef" command and see only the first 2 lines at the top and empty space below. In some cases the new command output does not appear at all, I see just the previous command result. The terminal blinks every 6-7 seconds, and for very short time I can see the proper content. As soon as the terminal loses the focus (mouse cursor moved, alt-tab, workspace change) it shows the proper content. However it never happens with roxterm, but it is a gtk-based program.

definitely similar issue here on nvidia. Usually I see the last 3 characters of the last command at the bottom line for about half a second, both in irssi and bash. Forcing redraw by switching workspace or minimizing it for a moment helps. I have been asking on #rxvt-unicode on freenode and they knew about the problem as well. You seem to be struck worse by the issue, and I hope the rxvt guys will address the issue soon.
