Extension dropdown with black border
STR: with WebRender enabled, click on a toolbar menu button from a WebExtension; or, with non-WebRender accelerated compositing, any menu of that type including from Firefox itself (e.g., the hamburger menu or the tab overflow menu). Doesn't reproduce with basic compositing. Probably needs a non-compositing window manager; I'm using FVWM and there's another report on i3wm.
Expected: the menu is shaped correctly and the transparent area around the outside is transparent.
Result: as seen in the attachment; there's a black background, like what I saw in bug 1480863.
This started after I did an OS upgrade on Debian unstable (a rolling-release distro); I don't remember exactly what was upgraded but it did include the nvidia graphics drivers (but may also have included GTK and/or Xorg packages). This reproduces with 66.0 (release) but not 60.6.0 (ESR).

I got a list of new/upgraded packages from /var/log/apt/history.log; it does include Xorg:
xserver-xorg-core:amd64 (2:1.20.3-1, 2:1.20.4-1)

This seems the same as bug 1479135

Maybe related — it also happened with non-extension menus using OpenGL compositing, which wasn't the case in bug 1480863 — but that was on Ubuntu 18.04 LTS last year, and this seems to have been a recent change in Xorg.

I guess it's related to desktop compositing (drawing with transparency) which may be disabled.
