[firefox 89] Can't enable Legacy OpenGL compositor
I use this workaround to fix tearing on my mediacenter powered by a intel baytrail hardware.
until v88, it was working fine.
With v89, the setting layers.acceleration.force-enabled=true has no effect. The "about:support" page reports Compositing: webrender (software) whatever the value true or false.
I had to downgrade to v88.
I'm not linuxy and this may be our bug, but try to set gfx.webrender.software.opengl = true (restart required).
The settings gfx.webrender.software.opengl = true does nothing. Compositing stays on webrender "(software)".
What about gfx.webrender.software?
no, it doesn't help :(

I've checked the firefox-nightly-91.0a1.20210614215408. It doesn't fix my issue.
