Any ideas?

So, I've begun fiddling with the tutorial example, but noticed that my fan was running a lot faster than it usually does. I checked the system monitor and noticed a CPU usage of around 50-60% when running the game code. This happens in both Firefox and Chrome. Is this normal? Any workarounds? It even slows down my code editor and other tasks. Sometimes it freezes for about 10 seconds, then continues but leaves the computer in a very sluggish state. - Scrolling vastly slowed down, programs shut down very slow etc. What is even more disconcerting is that nothing in the system monitor indicates any resource hog after I shut the browser down, yet the problems persist until I reboot. PS: I run Ubuntu 12.04 on a a i5 quad-core 2.5 GHz, 4 GB RAM. Bonus question: When upgrading from 1.1.3 to 1.1.5 gravity seems to get botched resolving A LOT slower than it should (and does in 1.1.3). What gives?
