Comment 22 for bug 1864365

This bug has also been reported upstream: https://bugs.chromium.org/p/chromium/issues/detail?id=1098379.

It was brought to my attention that chromium ships its own copy of fontconfig, it could be that this affects the way it writes to the cache.

I'll test building the snap with use_bundled_fontconfig=false, let's see if the problem goes away.
