Screenshot of the described glitch

Description of problem:
I'm using an r300 card (mobilityRadeon 9700) with a recently upgraded Fedora 10. On certain sites (example: http://www.vgcats.com/) Flash embeds get painted over with grey if you scroll them off-screen and they only get refreshed if there is an animation in that part of the embed or you drag a different window over it (see my attached screenshot). The VESA driver doesn't produce such glitches and the Opera browser doesn't seem to be affected (didn't have the opportunity to try WebKit, yet). Also disabling render acceleration didn't help. Also, there are certain sites which don't have this problem, perhaps because they only have a white background. The one site I know is http://www.failblog.org/ .

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

How reproducible:

Steps to Reproduce:
1. Open Firefox/Epiphany/Mozilla
2. Load www.vgcats.com
3. Scroll down to the mentioned Flash embed
Actual results:
The previously invisible parts are now covered in grey (see my attached screenshot).

Expected results:
The Flash embed should be perfectly visible.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf, if available) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf (if you have one) whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

XServer config

Deleting/Renaming this file didn't change anything.

XServer log file created during regular use

Also note: Modifying the values for "RenderAccel" didn't do anything except for "XAA" freezing X (as expected).

Well, looks like this isn't a bug after all.

I just had to do a complete fresh install of Fedora 10, because GRUB had spazzed out leaving me no other option than wiping my system partition. Anyway, either you just released a fix at the same time or the issue only appeared on my system after upgrading. Anyway, this bug can be closed, now.
