[External] : Re: XWayland > Wayland Drag and Drop on Fedora 35 does not work.

[Alexander Zvegintsev]

Hi Olivier,

Thanks again for fixing #2042 
<https://gitlab.gnome.org/GNOME/mutter/-/issues/2042>. It seems fixed in 
Gnome 42, however another issue I mentioned during one of the meetings 
is still persist.

It is related to the drop performing in wrong window. I've just reported 
it as #2136 <https://gitlab.gnome.org/GNOME/mutter/-/issues/2136>

Thanks,
Alexander.
