Why am I getting grayed-out windows in Ubuntu 12.04? I need to specify that I am talking about the windows themselves being grayed-out and the application frozen; I'm not referring to items on a drop-down menu being grayed-out.
I have plenty of memory (8 GB) and an appropriate AMD processor.
This is driving me crazy. I didn't encounter it until Ubuntu 11.xx. Lately, performance has been terrible, especially in Firefox (which crashes all the time). I feel like I'm wading in quicksand. I click on a link and have enough time to go get a cup of coffee before I get to the new window.
I would greatly appreciate it if someone could tell me what this gray stuff is and what I can do about it.
