Expected results: The popover should have been shown with no background.
Also: * My Nightly version is 57.0a1 (2017-08-16) (64-bit) * This problem happens with gfx.webrender.enabled * Does not matter whether gfx.webrendest.enabled or gfx.webrender.layers-free are true or false * I reproduced this bug both on i3 (X.org) and gnome-shell (Wayland)
Making this not blocking release as it's Linux-only and the initial release will be Windows-only.
OS: Unspecified → Linux
Hardware: Unspecified → x86_64
If I open a popup with webrender enabled, the following terminal message is outputted: ERROR:webrender::frame: ERROR: Invalid window dimensions! Please call api.set_window_size()

I have switched to the Developer Edition as my main browser since filing this bug and I can't reproduce it there. However, I can still reproduce it with Firefox Nightly 58.0a1.20171104, with the small difference that the area aroud the popover is now white instead of red.
