I just installed Ubuntu on my pc. I installed it within Windows XP. Xp is working fine. When I am browsing the internet in Ubuntu and I minimize the screen or decide to open another window it loads very very slowly. When I move the mouse around it shows the page trying to load. On XP I can surf the internet just fine no issues. I dont use Firefox in XP but I have it on Ubuntu. Is this a Firefox issue or something in Ubuntu?
