display artefacts with ati card

[calanor]

I am using fedora 13 x86_64, i have ati 3650 hd card and i am using oss drivers.
Everything on my screen seems to leave trailing shadows, and this isn't limited to fedora 13, but fedora 12, ubuntu etc when i am not using the fglrx driver.
One time when using ubuntu 9.10 i installed backfill packages to remove the minimize, maximize lag with fglrx driver, then too these artefacts appeared.
Also the intensity of the shadow effect varies.
Is someone else getting this behaviour?
can anybody tell me where to report this bug?

i have attached a screenshot.

Since you are experiencing the problem in F13, you could report it for Fedora at

https://bugzilla.redhat.com/

What a screenshot shows is what X was trying to render on your screen at the time, it's not exactly a 'photo' of the screen, although that's the intended effect. It's complex, but depending on where in the rendering pipeline the bug is, it may show up on the screen but not in the screenshot.
