Attachment: 2020-08-30-041722_2048x1152_scrot.png

• Hardware: Raspberry Pi 3b+ (supports GLES 2; the Pi 4 should support GLES 3.1)

• OS: https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2020-05-28/2020-05-27-raspios-buster-arm64.zip, upgraded to Debian Testing. (Tutorial)

• Nightly 81 2020-07-27: Linux AArch64 taken from Treeherder. I haven't found more recent ones and also haven't gotten any update.

• Started with $ MOZ_X11_EGL=1 ./firefox.

• Problems: Transparent tooltips/select fields, often missing tab text, empty address bar until clicking into it, can't highlight text in this textarea here, my avatar has a quadratic hole in it

I haven't found more recent ones and also haven't gotten any update.

It's not gone. bug 1650208 restricted this task to autoland:
If we see a release here, change its url from central to autoland, open Treeherder > Linux AArch64 opt > Artifacts > target.tar.bz2.
(If it's not there check one build before.)

Reconfirmed with latest autoland Arm64 Nightly on a Raspberry Pi4 8GB.

(The Pi4 also supports regular WebRender via GLES 3.1 which only seems to have a scrollbar glitch and a WebGL problem (a wall of full small tiles all showing the actual WebGL content). I want to file two separate bugs for it.)
