Same thing happens with just screencasting terminals, browser, anything really...but i noticed there are moments when it happens really rarely, doesnt look like its related to LOAD on my system thou.
I m not really skilled this kind of stuff, so please ask for anything you need to help me, i ll answer instantly (on my mail at least).
