FF77: 100% CPU while lid is closed on Debian/Linux

Dear community,

I'm encountering the following problem:

While the lid of my Lenovo P1 with Debian OS and XFCE w/m is closed, Firefox 77 uses one core @ 100% constantly. Using profiler.firefox.com didn't show any unusual activity at all. Other tools like about:performance don't help since the lid is closed while it happens. As soon as I open the notebook, CPU usage drops back to normal levels instantly.

Any ideas how to debug or where to look for?

Best Markus

Maybe missing information:

  • It happened with older versions, too, not exclusively related to v77
  • Debian OS flavour is Sid
