[Bug 1959747] Re: [upstream] Very high CPU and slow responsiveness in Thunderbird 91
I now discovered, that webrender is disabled by default in Firefox 101 on Ubuntu. So the question is, why it is enabled by default in Thunderbird. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1959747 Title: [upstream] Very high CPU and slow responsiveness in Thunderbird 91 To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1959747/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

From another side I got the hint, that miss-configured (web)rendering could be the source of the problem and cause lots of time spent in error logging.

I'm having similar problems in 1:91.10.0+build1-0ubuntu0.20.04.1 with Thunderbird's CPU usage well over 25 % and for long periods and additionally causing root process Xorg to consume 15 % CPU.

If I revert the above settings then the problem gets even worse.

I'm having similar problems again in 1:91.9.1+build1-0ubuntu0.20.04.1 with Thunderbird's CPU usage well over 100% and long periods of not responding since the update.
