 Tor Browser 9.0.4 (based on Mozilla Firefox 68.4.1esr) (64-bit)

 Example URL of a poorly rendered webpage:
 https://www.erowid.org/general/about/about.shtml

 It's the worst with the smaller text.
 I'm attaching a cropped screenshot of the area where it's in particular
 easy to see. 2nd image = the same but with underlined areas with the most
 extreme rendering errors.
 (by the way, headers are unaffected because they aren't actually text,
 they are images)

 AFAIK, the text should be rendered the same way on all platforms to avoid
 fingerprinting. But if this is platform specific bug, then I can provide
 any info about my hardware/OS/etc. privately to help solving this bug.

 The same page renders just fine in Firefox 72.0.2 on the same system.
