**Steps to reproduce**
1. Set gfx.webrender.all to true and gfx.webrender.allow-partial-present-buffer-age to false (see Bug 1695771) and restart Fenix.
2. Open https://www.swr.de/swraktuell/rheinland-pfalz/zahl-der-corona-infizierten-in-rheinland-pfalz-100.html or https://www.swr.de/swraktuell/rheinland-pfalz/index.html or https://edition.cnn.com/

**Expected result**
Websites are displayed normally with all glyphs visible.

**Actual result**
Intermittently, glyphs are missing, see the attached images, red boxes are added by me. `gfx.webrender.allow-partial-present-buffer-age` can be set to `false` (see Bug 1695771) or `true`. Thus, at least changing the flag does not regress this bug further.
