I'm using The Dark Reader extension with Nightly (Build ID 20200225214332). When I set gfx.webrender.all and gfx.webrender.split-render-roots both to true on Fedora 31 (RTX 2070 with v440.59 drivers), content in an idle tab disappears when I switch back to it, as shown in the attached screenshot. Setting gfx.webrender.split-render-roots to false and keeping gfx.webrender.all set to true causes the problem to go away, as does simply disabling The Dark Reader extension.

gfx.webrender.split-render-roots is deprecated so you should just turn it off.
