@mdeslaur: The best workaround is to disable hardware acceleration in flash. Removing vdpau will break the large amount of software that uses it correctly. Also, the bug only affects nvidia users because only nvidia cards and one extremely obscure S3 chipset provide vdpau support. If anyone has tested this on a S3 Chrome 400 card with vdpau drivers installed, I would be extremely interested in the result.
