[nVidia Quadro FX 1400] Screen gets corrupted, when accelerated.
Last modified: 2012-04-17 15:23:10 EDT
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):
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.
Enabling the NoAccel option seems to help (at the expense of making certain
things, like scrolling in Firefox _painlfully_ slow).
