I've hit an issue, which I believe I've now isolated to have come from upgrading fontconfig (and related packages) from 2.12.6-0ubuntu2 to 2.12.6-0ubuntu2.3 from -proposed: if I start Firefox and afterwards start Gparted or Synaptic, Firefox starts eating up all of my CPU. Eventually all letters in the Gparted/Synaptic UI turn into boxes.
Syslog typically then says something like below: Dec 4 13:41:50 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:50.995: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Sans 11' Dec 4 13:41:50 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:50.995: font_face status is: out of memory Dec 4 13:41:50 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:50.995: scaled_font status is: out of memory Dec 4 13:41:50 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:50.995: shaping failure, expect ugly output. shape-engine='PangoFcShapeEngine', font='DejaVu Sans 11', text='Päivitä' Dec 4 13:41:51 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:51.007: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Sans 11' Dec 4 13:41:51 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:51.007: font_face status is: out of memory Dec 4 13:41:51 saegusa synaptic.desktop[30027]: (synaptic:30028): Pango-WARNING **: 13:41:51.007: scaled_font status is: out of memory The computer has 32 GB of memory and there's plenty still usable when this occurs, so the OOM seems incorrect to me. To be sure, I rolled back entirely from -proposed (which caused the issue to go away), then re-enabled -proposed and upgraded just fontconfig, and the issue reappeared. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803534 Title: Backport uuid based cache file naming scheme To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/1803534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
