OpenGL Renderer window appears in tab list when playing a video

[Michael Gratton]

Every time a web page plays a video in Epiphany, a window named "OpenGL Renderer" appears in the gnome-shell alt-tab list (but not in the overview), one for each video. If I have several pages open with several videos, I get several of these phantom windows. Selecting the window in the list does nothing.

This started happening sometime during the beta, it didn't happen under 17.10 or after first upgrading to 18.04.

Status changed to 'Confirmed' because the bug affects multiple users.

Most probably Wayland-specific.
