## Mark Kirkwood (mar...@paradise.net.nz):
I'm on 7.1 Prerelease refreshed a few days ago. I've noticed that Firefox 3 (3.0.4, but 3.0.3 was the same) displays snippets from ones desktop on some webpages (yahoo and youtube being the 2 most recent).
Image rendering was optimized in Firefox 3, so it breaks with a lot of xservers (seems as if some pixmap rendering code is broken in X and firefox triggers that problem). Try setting Option "XaaNoOffscreenPixmaps" to "true" in the "Device" section of your xorg.conf.
Thank yo so much for this suggestion.
I have been annoyed by this odd problem since I started using Firefox3 and this finally make things work correctly. I think this needs to be in a FAQ somewhere until/unless the Xorg driver is fixed.
In any case, I was seeing this with an ATI Radeon X300 M22 graphics chipset. I don't seem to see it with my nVidia GeForce 7800 GT based system. I don't THINK I see it with my old MGA Matrox G450 , but I won't have my eyeballs in front of that system until next month, si I am not sure.
Anyone seeing this with any other graphics device that does not use the RADEON driver?
Happened on my MGA G450. Removing the XaaNoOffscreenPixmaps option from xorg.conf shows that some scaled images in Firefox3 3.0.4,1 still render as either black boxes or partly black. It used to also show the desktop background in some windows, but I didn't see that in a quick check.

Some day I'll replace that ancient system (a Pentium-III) with something more modern, but thanks to you, the G450 keeps doing the job for me.
