Yeah, that's better.
Mainly scrolling is way less sluggish.
Have come to think that the main problem may be facebook (else i only use phpbb-forums, wikipedia and such. So it might well be that twitter and such is borked too, but as i don't use it ... )
in general the desktop graphics seem to be very sluggish. I didn't realize, cause i usually don't move windows around.
I had such problems years ago, julian67 knew how to handle it, but it didn't help that much. With a certain upgrade it was better (kernel or such, i don't know).

memtest reported no errors.
looked at uzbl web-browser. Too confusing and it didn't help (as far facebook is concerned).
