Status of Wayland implementation on nVidia graphics cards

[Christian Ohrfandl]

Hi Roman,

thank you for the information! I have decided to go for a bug report (a 
few days ago). You can find all the details (incl. logs, pictures and 
videos (links to youtube) right here: 
https://bugs.kde.org/show_bug.cgi?id=385007. Would appreciate your analysis!


Cheers,
Christian
