I don't know how to best describe the issue with my LMDE 64 bit. Independent of the browser the youtube video slows/stagnates while the sounds plays on. I have already tried to change from flashplugin-nonfree to flashplayer-mozilla without any improvement. I am mainly using chrome but the issue also appears in firefox or opera. If it is not related to flash there might be a connection to the very slow Picasa performance. Using Picasa on this system is a pain while it is no problem on the ubuntu-based mint versions. What makes the difference?
Thanks for any feedback/idea!
