Bug 1735939 - Never use CreateConfigScreen() on EGL on Linux, r=stransky
(deleted), text/x-phabricator-request
Details

Resembling bug 1699864, enabling gfx.webrender.software and gfx.webrender.software.opengl makes the window turn white on EGL (not on GLX). While we currently don't plan to support this option on Linux, it useful for developing.

Can't reproduce with Gnome Xwayland, Debian Testing, Intel Graphics 6100 (BDW GT3), Mesa 21.2.2.
mozregression --launch 2021-10-14 --pref gfx.webrender.software:true gfx.webrender.software.opengl:true

status-firefox95: --- → disabled

There is only one case left where we use the CreateConfigScreen()
path on Linux: on Software OpenGL / gfx.webrender.software.opengl:true.
It is not used when using WebGL with SW-WR.

It triggers an analogous bug like the one fixed in D109737. Given
that we disable EGL on 16bit configs already, also force 32bit
in this case.

Depends on D128411
