I am still experiencing this issue. Not just with Android Studio, it also happened when loading a file in Gedit. CPU2 goes to 100% and stays there, while Gedit or AS stops responding. In the System Monitor "Processes" tab, no processes are taking more than 1 or 2% of a CPU. The process that froze has 0%, but >600Mb memory usage. The process unfreezes typically after 5 minutes. Almost always it's cpu2, once it was 9, occasionally it's cpu3. I have a 6core cpu, 16G of memory.

Status in lightdm package in Ubuntu: New Bug description: Since a few days, when I use Android Studio, my screens freeze. Nothing works. With alt-crtrl-F2 I log in to a shell window, restart lightdm, then it works. Except on the last freeze, now I had to restart the computer. When restarting lightdm, a popup said "system in low graphics res, cannot detect your settings". I have reported the but to Android Studio developers. But a program, even a big one like an IDE, should not be able to crash my computer.
