Description Máirín Duffy 2010-05-06 14:15:00 UTC
Description of problem:
I've been noticing since I started running the RHEL 6 internal beta this week, Firefox in RHEL 6 randomly seems to present corrupted images. I've noticed this on planet fedora (see screenshot), on, on - basically, on a wide variety of sites. It tends to happen to smaller images around 100x100 (avatar-sized graphics seem to be the most frequently affected.) I have noticed that sometimes the page and graphics will load fine, then I'll switch windows, and when I switch back one or two images on the page will be corrupted when they were not corrupted before I switched windows.

Version-Release number of selected component (if applicable):

How reproducible:

I don't think it is very easy to reproduce, but it happens very frequently. I'm not sure what is triggering it, but as I mentioned and blog planets seem to trigger it a lot, and it also may be associated with switching windows back and forth.

Comment 2 Máirín Duffy 2010-05-06 14:25:18 UTC
It seems really easy to reproduce if you visit and search for something (try searching for 'pony' - the thumbnails the site generates seem to be the perfect size for triggering the issue)

What X server, kernel, and graphics driver?

Comment 5 Máirín Duffy 2010-05-06 20:53:57 UTC
Hi Bill,


the driver is the "intel" driver

Comment 6 Matěj Cepl 2010-05-07 00:03:25 UTC
I can see it from time to time myself. I think, it's the time to take a look at it.

Comment 7 Michal Haško 2010-05-07 07:21:53 UTC
I confirm this issue as well.

screenshot of weird artifacts in vim

I don't know if it's related, but on the same system I'm also seeing these weird artifacts in vim (see the screenshot). They're towards the bottom of the screen.

Comment 9 Matěj Cepl 2010-05-13 18:24:14 UTC
I will go out on the limb and claim that this one of many many many presentations of bug 571785.
