[Spice-devel] Working seamless mode

[Roland Baudin]

Hi Jakub,

thanks for your detailed answer. I understand there may issues with 
Wayland, but IMHO the vast majority of Linux users don't use Wayland yet 
(too many problems!). So I still think your work is very useful. I use 
the seamless mode at home and at work in Ubuntu 20.04 and it works very 
nicely.

But I understand it's difficult to maintain theses patches and make them 
evolve.

Have a nice day,
RB
