Public bug reported:

The upgrade in nvidia-current to 256.35-0ubuntu1 has introduced video tearing with hardware that has always performed fine thru the 195.36.24 drivers ( both in maverick and in lucid.
While the hardware is approaching becoming obsolete, I'm sure many still use agp and maverick could remain an option.

Card here is  G70 [GeForce 7800 GS]

As a test, with a fully updated install (07/04), reverted back to nvidia-current 195.36.24-0ubuntu2 and playback returned to being perfect.
Obviously I (or others) can't keep this nvidia package for long in Maverick so am requesting that Maverick at release offer an alternate nvidia driver(s) if possible and if so have it or 1 choice be the 195.XX driver.

While clearly the 256 driver offers improvements, most of them are only realized on newer pci-e hardware, for agp there's nothing gained and most certainly something to lose.
Note that the 7000 series is not too fond of the 173 drivers, so that's not an option ( not that they are usable atm anyway
