Hi, I thought I succesfully updated Feodra 20 to 21, but after rebooting I started to notice strange graphics bugs like duplicating mouse cursor, short freezes etc.. I'm running Fedora on my Lenovo Z580 notebook with dual gpus.

[root@localhost vgaswitcheroo]# lspci -v | grep VGA

Bugs are also visible after clean install of FC21.

I also heard of glitches for another lenovo (x1 carbon) user with fedora 22, I guess it happens at every release. If you have older hardware it tends not to happen.
