Bug Description
I have booted the computer about half an hour ago. Since the very beginning, I noticed the fan spinning at high spin so I launched "top", and noticed that Xorg was consuming about 50% CPU and another process called "at-spi2-registr" is consuming another 20%.
Since then, They have continued consuming that amount of CPU constantly, all the time, whether or not I was doing anything. The only applications I opened are a terminal where I'm running top and the browser where I've been browsing Facebook. Before I launched the browser and after I closed it, CPU usage by these processed has never gone below 50% and 20% respectively.
This is fucking ridiculous.

Interestingly, killing the "at-spi2-registr" process has made Xorg's CPU consumption go down to normal.
