Steps to reproduce:

I open a webpage:

I think that this is connected with this font: https://fonts.gstatic.com/s/oswald/v13/dI-qzxlKVQA6TUC5RKSb3xJtnKITppOI_IvcXXDNrsc.woff2

Several of the downloadable font resources (from the Google webfonts service) used by that page are rejected by the OpenType Sanitizer due to errors in their opentype layout tables (see error messages in the browser console). This is basically the same issue as described in bug 1331737 and other reports.

You can work around it by setting "gfx.downloadable_fonts.otl_validation" to "false" in about:config (which is the setting we ship by default on release channels, so regular users won't normally see this issue, but developer builds expose it to raise awareness).
