Bug#1070972: Same bug after an upgrade of libwebkit2gtk-4.1-0:amd64 to 2.48.5-1~deb13u1

[Peter Müller]

After libwebkit2gtk-4.1-0:amd64 got upgraded to 2.48.5-1~deb13u1 today, nothing changed: the contents of the Web pages is not shown, i.e., the canvas remains blank.  The installed nvidia-driver has version 550.163.01-2.

The workarounds are running epiphany-browser with
WEBKIT_DISABLE_DMABUF_RENDERER=1
or
WEBKIT_DISABLE_COMPOSITING_MODE=1

Grateful for looking into it.
