Public bug reported:

This machine is being used a lot to cast to Chromecast using Chromium.
Some days Chromium is regularly freezing every 10 minutes or so. It is
necessary to restart the computer to  get casting again. Regularly, the
freeze causes the "force close" or "wait" pop up to appear. If I am
quick to react, I can quit Chromium and a reboot gets things going
again. But if I am too slow, sometimes the whole desktop freezes
including the mouse and I need to Alt-SysRq+B.

If I am casting and during a boring bit I want to check my emails, then
running Thunderbird causes the whole system to slow down, and the
casting to reduce resolution and only update the screen every 10 seconds
or so.

Please let me know if there is anything I can do to help diagnose the
problem.
