(I should note - lightdm-gtk-greeter
is at 0% GPU utilization, as you'd expect)
I think you are probably right about it being related to the animation. I'd be interested to know if you see the same behavior with our 3.0.0 release candidate.
Whoops, I got this issue mixed up with #139. I have a feeling they are essentially the same issue though.
Ah, okay. I'll build and give 3.0.0 a try later tonight :)
My machine is quite beefy - an i7-6900K CPU and an NVidia GTX 1080-Ti.
Purely by coincidence, I happened to run
nvidia-smi
in an SSH session after remotely rebooting my machine. The only thing using the GPU after a reboot was lightdm running in Xorg, and yet it reported a consistent ~38% GPU utilization.A few hours later when I arrived home, I SSH'ed in again before logging in and confirmed my GPU was still pegged at >35%. Immediately after logging in (and therefore dismissing lightdm-webkit2-greeter), GPU usage dropped back to 0%.
I understand that there is some overhead associated with running WebKit, but consuming more GPU resources than most triple-A video games just to display a wallpaper seems so ridiculously excessive as to qualify as a bug. Especially considering that machines often stay in lightdm for hours on end after an unexpected reboot until the user gets to their desk, this bug represents a significant waste of energy and hardware wear-and-tear.
My
lightdm-webkit2-greeter.conf
is pretty much Arch's stock default, pasted below:
