Status: RESOLVED WONTFIX

When setting gfx.webrender.all and gfx.webrender.split-render-roots both to true in Nightly (Build ID 20200225214332) on an unsupported WebRender platform like Fedora 31 with an RTX 2070 and v440.59 drivers, the address bar drop down is only a few pixels in height. Setting gfx.webrender.split-render-roots to false and keeping gfx.webrender.all set to true causes the problem to go away.

gfx.webrender.split-render-roots is deprecated so this is expected behaviour.

Can you point me towards any other experimental WebRender bits I can flip in my hunt for crashes? Thank you.

I don't think there are any to try on Linux. Every is turned on by gfx.webrender.all=true
