Description Aleksey Nogin 2006-08-30 21:03:17 UTC 
Description of problem:

Often, a screen gets corrupted. Namely: windows get garbled, background gets
garbled, xrefresh does not help, forcing something to redraw (e.g. by moving a
different window on top) sometimes helps "reveal" parts of the corrupted window,
but not for long.

Switching to a text console and back usually (always?) helps to get rid of the
problem (until it comes back again).

Version-Release number of selected component (if applicable):
xorg-x11-6.8.2-1.EL.13.37

How reproducible:

Fairly reproducible - most often gets triggered by browsing to some complex page
(Slashdot story on GPL msconceptions, for example, triggered it 3 times in a row
;-) ) in Firefox. 

Additional info:

Enabling the NoAccel option seems to help (at the expense of making certain
things, like scrolling in Firefox _painlfully_ slow).

No further non-security updates are planned for xorg-x11 in RHEL4.  If this issue is not addressed in RHEL5 or newer, please update the affected product version and reopen this bug.
