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.<\/p>\n
Syslog typically then says something like below:<\/p>\n

The computer has 32 GB of memory and there’s plenty still usable when this occurs, so the OOM seems incorrect to me.<\/p>\n
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.<\/p>\n","protected":false},"excerpt":{"rendered":"
