We need this, I have the same problem. Feature is great but becomes problematic when you face dire situations in game because you click the pop-up window accidently or when you are looking around in game mouse goes that window etc...
@leocg In my case the good example is the Opera Forum page itself:

The CPU usage circles around 50-80%. When I close the forum pages, the CPU settles down.
