        <pre>Window shadows are borked for me in AC mode. This bug *seems* to affect amdgpu and noveau users, but not Intel graphics.

See: <a href="https://gitlab.gnome.org/GNOME/gtk/issues/1401">https://gitlab.gnome.org/GNOME/gtk/issues/1401</a>

After some debugging with Company we determined "the shadows are NOT messed up in the image passed to gdk_window_end_paint_internal()" and that "we use OpenGL (in gdk-wayland) to send the window contents to the compositor and it seems that is going wrong once Webkit gets involved"</pre>
