Webrender in ff on librem 5

It looks like Firefox currently uses the software fallback for Webrender when looking at about:support. (It says “Webrender (software)” next to “Compositing”)

Anyone know the reason? Webrender should be substantially faster than its software fallback.

Likely because the Librem5 GPU doesn’t support features needed by WebRender.

Just skimming here


and I happened to notice that Firefox’s about:config page appends a new key/value pair, just for me :slight_smile:

“gfx.blacklist.webrender.failureid”: “FEATURE_FAILURE_OPENGL_LESS_THAN_3”

Anyone know what the status is of GLES 3 in etnaviv?
