Please keep each bug report about a single issue. This bug will now be about only "stuttering when dragging windows around".

I happen to have a bunch of fixes for this on the way which are being tracked here: https://trello.com/c/pe5mRmx7

Assuming this isn't somehow an nvidia-specific issue.

[Daniel van Vugt (vanvugt)]

Can you say whether the problem applies to all applications' windows, or just some?

[Daniel van Vugt (vanvugt)]

Oops. Actually this issue is likely just lack of support for the GTX 1080 in the nouveau driver.

Can you please try enabling the Nvidia driver instead? It appears to be installed but not in use.

[Nicholas Davis (zapmaster14)]

Hi,

I will try and find out how to enable it, will report back asap.

[Nicholas Davis (zapmaster14)]

Hi,

So far I have been unable to find out how to enable the drivers as you suggested I will continue searching.

Thanks

It appears the problem is most likely this:

[ 989.990] (WW) modeset(0): flip queue failed: Device or resource busy
[ 989.990] (WW) modeset(0): Page flip failed: Device or resource busy
[ 989.990] (EE) modeset(0): present flip failed
[ 990.106] (WW) modeset(0): flip queue failed: Device or resource busy
[ 990.106] (WW) modeset(0): Page flip failed: Device or resource busy
[ 990.106] (EE) modeset(0): present flip failed
[ 990.122] (WW) modeset(0): flip queue failed: Device or resource busy
[ 990.122] (WW) modeset(0): Page flip failed: Device or resource busy
[ 990.122] (EE) modeset(0): present flip failed
[ 990.147] (WW) modeset(0): flip queue failed: Device or resource busy
[ 990.147] (WW) modeset(0): Page flip failed: Device or resource busy

where the Xorg 'modeset' driver is trying to talk to the kernel 'nouveau' driver.
