[i915gm] [i915] random text corruption

[toobuntu]

Binary package hint: xserver-xorg-video-intel

I only noticed this in firefox, fixable with a page reload. Desktop Effects not enabled.

Attached is a screenshot of the corrupted text in gmail. It happened on other websites, too.

If this only happens in Firefox, it might be an extension or a greasemonkey script that's changing the page. Have you tried running Firefox in safe mode?

[toobuntu (toobuntu)]

It's almost certainly not a firefox issue, but a problem with UXA or DRI2 in the new intel graphics driver. See Bug 422072, where the reporter had similar text corruption problems with gnome-terminal as well as firefox.

I only have adblock plus, noscript and flashblock extensions. None of those _should_ be at issue here. At any rate, running in safe mode would be pointless right now as I don't know of anything specific to trigger the errant behavior.

This bug report has been inactive for quite some time and in the meantime Ubuntu has moved along. I hope the reported problem has been resolved in the current version of Ubuntu. If it has not and there are people willing to follow up with information collecting and testing, it is best to file a new bug report with the latest Ubuntu development version (currently 10.04, but soon 10.10), using the ubuntu-bug command if possible. Feel free to mention the bug number of this bug.

We are sorry that we are not always have the capacity to look at all reported bugs in a timely manner. Occationally we have to purge old bug reports where no progress has been made, whether it is due to reporter not being able to respond or lack of manpower on the Ubuntu side, in order to keep our list of "active" bugs current. Sorry for the inconvenience this may cause.

Here are a few tips that will increase the chances that your bug gets priority:
* Read https://wiki.ubuntu.com/X/Reporting
* Browse https://wiki.ubuntu.com/X and see if there is some relevant information for you problem
* Respond quickly to questions from triagers
* Try changing things to see if the behaviour changes, e.g.
  * A new mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D (more information at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds)
  * The xorg-edgers PPA: https://launchpad.net/~xorg-edgers/+archive/ppa
  * Various options in `/etc/X11/xorg.conf` (see `man intel`)
* Browse other bug reports to see if you find a similar one and provide the information that is being asked for there.
