If the GL context MakeCurrent fails, then we can end up in a state where mEGLImage is valid, but there is no context:
https://searchfox.org/mozilla-central/rev/fc757816ed9d8f8552dbcb96c1f89f8108f37b2a/widget/gtk/DMABufSurface.cpp#692

And when we release it, we can trip this assert:

Pushed by aosmond@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/3606ab5e28ab Ensure DMABUF calls MakeCurrent before creating EGLImage objects. r=gfx-reviewers,lsalzman
