Running E ( git ) in wayland mode, when I launch firefox, the window contents are never rendered. The window appears to be transparent, but when you move or resize it, it becomes clearer that the window contents are in fact whatever was underneath the window when it was first created. Firefox doesn't appear to crash. The titlebar ( a gtk title bar ) only is rendered, and I can see the name of the tab I last had open.
- the default Arch build of firefox ( which is supposed to support wayland )
- firefox-developer-edition - also an Arch package, and also supposed to support wayland
- building firefox-wayland-hg from the AUR repository
All behave the same way.
I've tried with GL and software compositing - also the same behaviour in both. When I take a screenshot with E, I get the same as I see on the screen.
I can run other gtk apps in wayland mode in E. I can run firefox in a Gnome/wayland session, with firefox in wayland mode, and it works ( quite well actually - tear-free netflix ... my goal here ).
I can run firefox in X mode ( with GDK_BACKEND=x11 ) and it works.
