Public bug reported:
I navigated to a website in Chrome (linledIn.com) and both Chrome and
Xorg started consuming around 100% CPU each (one was actually
significantly above 100% but I can't remember which one).
Then I closed Chrome entirely (and I check there was no Chrome process
left), but Xorg kept consuming around 100% CPU. No other process was.
I closed all applications I had opened, but nothing stopped Xorg from
consuming around 100% CPU while nobody was doing nothing. I had to kill
Xorg.
It might have been a complete coincidence that Xorg's crazy CPU usage
started when I opened that website in Chrome, or it might actually have
been caused by it, even by a bug in Chrome. But even if that is the
case, if an application can cause Xorg to consume 100% CPU and then not
stop even after the application has been closed, that is a bug in Xorg.
Also, something quite similar happens to me very often:
sometimes I open Google Maps in Chrome and (not every time, far from it), the
same as described above happens, that is, both Chrome and Xorg start consuming
a lot of CPU. However, in those cases, usually when I close Chrome, Xorg's CPU
consumptions goes back to normal (and then I'm able to reopen Chrome and
everything works normally).
This was the first time that Xorg's abnormal CPU consumption persisted after
closing Chrome which seemed to have triggered it.
I'm not sure whether the two cases are actually caused by the same issue or not.
I know I'm providing little information but this is all I have.
Note that the issue is critical.
