Details
On my pixel 3 (Adreno 630) I get bug 1686800. Additionally if the foreground tab is about:support, and I turn the phone off and on again, I get a black frame for content. Reloading doesn't fix it. Switching tabs renders the tab I switch too, but when I switch back to about:support, nothing paints. I see the previous tab contents despite not viewing that tab.

Actually, switching tabs is generally broken, you never know what you're going to get. Black rect or the previous tab's contents.

:jimm, how did you enable software fallback on android? With the following prefs changes?
- gfx.webrender.software = true
- gfx.webrender.software.opengl = true

Only the first, I'll re-test with the second set.

Only "gfx.webrender.software = true" enables RenderCompositorSWGL that we do not expected to be used on product.
With both prefs, RenderCompositorOGLSWGL is used that need to be enabled on product.
