There are little green dashes across the screen randomly. This is on a Toshiba Satellite Pro laptop with an RV620 Radeon HD 3400 display.
Throughout using Karmic this was absolutely fine using the Radeon driver. To get 3d support I started using the Xorg-edgers PPA and then 3d support was fine too.
Now from upgrading to Lucid the display corruption is there from Plymouth onwards. It does start off worse and then get slightly better on one laptop but on an identical laptop the corruption is slightly worse. Obviously the clocks are slightly off between laptops. It's still not perfect on any though.
Using nomodeset on the kernel options sorts it out but then the virtual desktop has to be set before changing display properties.
I've tested with the mainline kernel (2.6.34-999) which is exactly the same.
As an aside, these Toshiba laptops seem to have a dodgy implementation of the RV620 - fglrx has always just hard-locked on X start, now this works but gives very bad display corruption. Using Windows on them is fine though so I can't blame the laptops specifically.

Got this bug too on Toshiba Satellite A 300 (Radeon 3470). Lucid with the latest updates installed.
