System feels slow - on a new laptop

Everything is very, very slow on my new laptop, but only when things are moving and only on manjaro

Hiya. On my recently purchased laptop I decided to install Manjaro, and once it’s installed every time I do something that requires more than a little movement (scroll on a website, watch a video, play a game, etc.), everything lags like I’m playing doom eternal on a Windows XP machine. I have the Nvidia drivers installed, and my cpu/memory usage is totally normal. I’m totally lost on why this happens. On Ubuntu based distros things run just fine, but everything is super slow on Manjaro and I can’t figure out why.

Firstly, please open a terminal (i.e console/konsole/terminal) and type “inxi -CG” without quote. Copy paste the result in here.

Which kernel are you using ?
uname -a
on console.

Linux manjaro 5.9.11-3-MANJARO #1 SMP PREEMPT Sat Nov 28 09:08:57 UTC 2020 x86_64 GNU/Linux

Somehow I got a feeling this is a wayland thing. Are you using Manjaro Gnome?

I am, but the same issue occurred with xfce.

Hmm, try disabling desktop compositor.

Edit:
And please check you system monitor if there is anything unusual with your CPU or RAM usage.

I’m not really sure how to disable that, I’m new to manjaro and gnome. Also, my CPU and RAM usage are normal.

Press Alt+Shift+F12 to temporary disable compositor.

This doesn’t look normal to me, what kind of monitor do you use and connection type?

(edit: Forgot that the poster uses a laptop which means a build-in monitor)

That because by default Manjaro doesn’t install xorg-xdpyinfo package. It’s normal.

After pressing the keybind you said the issue persisted.

Oh, are you sure your CPU usage is normal? From inxi output 2 of your CPU cores seem to have quite high usage.

Huh, now that i look at it again the are way up, only 2 at a time though.

edit: 2 cores at a time, that is.

Do system monitor show what’s taking that much of your CPU cores?

No, it’s actually quite strange: everything shows as 0% usage. Checking back CPU usage spikes when watching a video, I didn’t catch that before. Definitely not 100% or anything like that, but higher than it should.

Mind that Nvidia should use Xorg by default and not Wayland.

I know. I’m just guessing. I haven’t use gnome in a long time, so I thought if there is a chance that they make wayland or modesetting as default (which activate wayland even in nvidia system, cmiiw). But, I guess I was wrong.

CPU usage while watching a random video off YouTube on Firefox. It is very much high, and system monitor doesn’t show that for some reason. I typed out what is using the CPU, because I couldn’t figure out how to copy from htop and I can’t upload images.
/usr/lib/Xorg vt2 -displayfd 3 -auth /run/user/100/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -novtswitch -verbose 3

Nearly 100% of my CPU was being used
