Bug#627952: xterm display freezes occasionally, will execute commands but not display keystrokes or results

[aj heller <drfloob@gmail.com>]

Package: xterm
Version: 269-1
Severity: important


xterm display will freeze intermitently, allowing commands to be run but not showing keystrokes or results. Oddly, if this "freeze" bug occurs when I'm typing, the freeze will eat the word I'm typing and display everything up to the previous space in the command. Alt-Tab and window resize both cause the screen to refresh and display everything, but not for long. It *seems* that after rebooting, it wont happen for a while, but when it does finally happen, it does so regularly.

I'm not sure what packeage is the cause. I thought it may be the graphics driver or something else, but the bug specifically affects my xterm usage. A similar "freeze" bug happens with flash, where alt-tab causes videos to unfreeze, but I'm not sure that's related.

Also, I was using testing/wheezy exclusively when this bug started (fresh install a few days ago). I included the unstable repositories to see if a bleeding-egde version of *anything* would fix these issues, but they're still happening.
