At some point, WebKitGTK calls gdk_gl_context_make_current, which is probably
this line of code:
https://github.com/WebKit/WebKit/blob/wpewebkit-2.42.4/Source/WebCore/platform/graphics/wayland/PlatformDisplayWayland.cpp#L113

Since gdk_gl_context_make_current is GTK, I also have to mention which version I use: (3.24.38),
see code line:
https://gitlab.gnome.org/GNOME/gtk/-/blob/3.24.38/gdk/gdkglcontext.c?ref_type=tags#L859

>From there on, I'm a bit stuck, but I have the feeling that some commits wrt defaulting to GLES
are not yet in that GTK version.
