after "upgrading" to 13.04 my flash video is playing, but not properly. The flash video is similar to a video screen being out of sync. The screen stays fine with the exception of the flash video. I am using a Dell gx270 with the on board Intel video card. I had an old Nvidia mx400 card that I threw into the AGP slot that fixed the problem, but it made the system unstable, I'm thinking because of the drivers. I have tried Firefox and Chrome all to the same end.
