Title:
fontconfig 2.12 in 18.04 causes firefox to freeze when launching
chrome
Status in fontconfig package in Ubuntu:
Confirmed
Bug description:
fontconfig version: 2.12.6-0ubuntu2
Related:
https://askubuntu.com/questions/1076412/firefox-freezing-with-100-cpu-
usage-for-30-seconds-when-launching-chromium
https://bugzilla.mozilla.org/show_bug.cgi?id=1495900
https://bugzilla.mozilla.org/show_bug.cgi?id=1411338
Steps to reproduce:
1) Launch firefox, open a few tabs
2) Launch chrome
3) Go back to firefox, and notice it starts being very slow, switching
tabs do nothing (the content area remains blank).
4) Backport fontconfig 2.13 from cosmic to bionic
5) Try to reproduce 1-3, be happy because it is now working fine!
I backported 2.13.0-5ubuntu3 from cosmic to bionic, if that helps. I don't
have the right setup right now to do a bisect from upstream or from debian
patches sadly.
