What is it with Nvidia and Xorg lately? Do you guys communicate on changes?
Something changed when I bumped up to Xorg latest:22.214.171.1242-1 in Debian Sid.
The Flash Plugin routinely stalls and acts as if it's waiting for a response from X server and only when I kill the plugin does the page with impending flash load.
Dumb games like CityVille and CastleVille are now eating > 600MB of RAM. It ran up to nearly 1GB today in the plugin alone with just 3 tabs open for both Chrome Unstable and Firefox 8.
