Comment 4 for bug 860509

I'm using Ubuntu 11.04 – since I upgraded to Natty Narwhal I see heavy graphics corruptions in Gnome 2.32.1, the Gnome panel is especially affected. I'm sure I already saw those corruptions in Ubuntu 10.10 (but I had the backports activated…). I'm sorry but I can't narrow this further down…

In addition I'm noticing increasing usage of my swap-partition. I have 4GB swap (don't ask me why) – within a few hours the graphics corruptions and the swap-usage increases until the whole 4GB are in use and the system freezes. I'm quite sure those symptoms are related…

I attached two screenshots showing different corruptions on Launchpad:

https://launchpadlibrarian.net/70632490/screenshot_stefan-nagy_01.png shows a permanent symptom only affecting context menus of the Gnome panel - in my case the gnome clock applet, the indicator applet and the applet used to switch between open windows using buttons (in german called 'Fensterwähler'). I *don't* see those corruptions when I open the context menus of the menu bar and the netspeed applet.

https://launchpadlibrarian.net/70632558/screenshot_stefan-nagy_02.png shows a symptom which appears after some time (an hour or more) and tends to get worse i.e. one Gnome panel part after another is affected.

I'd really appreciate any help with this, please tell me if I can provide additional information.
