LP #1566651 doesn't seem to be caused by font cache -- teddybeermaniac@lp reported that force-regenerating the cache didn't solve the blurry bitmap problem.
It appears that 2.11.94 doesn't show the problem, so the fix should be somewhere upstream. After some commit-log grepping (https://cgit.freedesktop.org/fontconfig/log/?qt=grep&q=bitmap&showmsg=1), 286cdc9 looks like the fix to me, and you may want to test and maybe backport that too. -- Regards, Arthur2e5
