I've got the same issue. Firefox on Debian on ChromeOS. Screenshot attached. This seems to be a new issue. Firefox 111.01

ra_hardy, could you attach the PDF? Maybe it is the same issue, maybe it is a new one.

Here's an example

On the front page, just the Capital S renders.
Firefox on Windows is ok

:ra_hardy, can you test with Firefox nightly (113) ?
I just tested with nightly on Fedora with Wayland or Xorg and it works for me in both cases.

Could try also to disable canvas acceleration ? i.e. in about:config, set gfx.canvas.accelerated to false.
