I can confirm that the bug described in the askubuntu.com link above is the bug I'm seeing; the workaround stated there (renaming `~/.fonts`) was enough to prevent it occurring.
I have fontconfig 2.12.6-0ubuntu2 installed (and my fontconfig-config is the same version). Should this bug report be moved to the fontconfig package, as apparently it's the underlying cause of the bug? Presumably it will be fixed if/when Ubuntu updates to a newer version of fontconfig. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856624 Title: Firefox freezes temporarily at 100% CPU when Chromium is opened To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1856624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
