Fedora23: slow performance with Wayland

This issue is present on the login screen or when logged in with Wayland. GNOME without Wayland works fine.

Mouse/keyboard input and graphical output (e.g. animations) freeze at consistent intervals. I get a few seconds of responsiveness followed by a period of waiting.

As long as I do not move the mouse or interact with the interface, I can type into the password field without experiencing any lag whatsoever. This lack of lag does not carry over to other text fields, though, including the terminal, GNOME search, and gedit (when logged in with Wayland).

@whitepeony thanx for report altought I suggest you to open a bug in bugzilla.redhat against wayland packages, but I just say a few things to you, first - wayland is under hard development, second - I know we can use wayland in Fedora 23 but error happen an the developer team are working very hard to correct this issues, third - primary was a decision to implement it as default sesion in fedora 24 but some things changes sometimes, more info here, Wayland-Not-For-Fedora-24

Is there a way to disable Wayland on the login screen?

No, just select gnome as default login screen...or edit cat /etc/gdm/custom.conf

I guess your graphics driver isn't ready for Wayland so Wayland needs to do all the rendering on your CPU instead of your GPU, which tends to be slower.

The mouse input lag is known:

As @hhlp stated: Wayland isn't ready yet.

His CPU seems capable of anything
