This bug was fixed in the package fontconfig - 2.12.6-0ubuntu2

---------------
fontconfig (2.12.6-0ubuntu2) bionic; urgency=medium

  * Upload proposed patch from upstream bug #103652. If the fontconfig cache
    was built on a system that has nanosecond timestamps and then later
    transplanted to one that doesn't - for example by mksquashfs as part of a
    live CD build - we consider the cache invalid and rebuild it during the
    boot process. Depending on the fonts involved, this can take a significant
    amount of time and potentially cause knock-on timeouts. The approach in
    this patch is to ignore the nanosecond portion of the cache's value if we
    get 0 when stat()ing the referenced directory, meaning it is considered
    fresh if the rest of the timestamp matches. (LP: #1749546)
