This looks like a duplicate of #19360 . We disabled webrender on affected devices in https://bugzilla.mozilla.org/show_bug.cgi?id=1712148, and https://bugzilla.mozilla.org/show_bug.cgi?id=1712290 tracks fixing the issue and re-enabling it.
@elsandosgrande Since you filed the bug, Firefox nightly should have been updated to have webrender disabled. Please let me know if your mum still sees the issue after updating!
@jamienicol Indeed, after updating Firefox Nightly today, the force-disable flag was not needed. Also, the two flags that were mentioned in that other ticket had no effect here as well.
Note: I tried looking for another ticket mentioning this issue, but I wasn't even sure which search terms to use. I tried looking for WebRender
, WebRender glitch
, and glitch
, not to mention just looking through the first dozen tickets that appeared in the tracker, but never thought to look for black rectangles
😅.

Force-disabling WebRender makes the graphical issues above stop, therefore I concluded that this is an issue related to WebRender (whether it's a driver bug triggered by WebRender or a WebRender bug, I don't know).

Note
Since this is my mother's phone and not my own, it will likely take some time for me to respond (this has been an issue for roughly two weeks now if memory serves, but I've only been able to get around to it today).
