I don’t know what kind of log I need to include but this is the situation I’m in.
Off of a fresh reboot, my system is laggy and slow…
What I mean is, programs start up promptly and all
but slow and laggy as in
-lots of screen tearing (when watching youtube or netflix)
-tons of cluttering? stuttering? when scrolling in web browsers
But!
All this goes away once I logout and log back in!
What could be causing this?
I can live with it but would be nice to iron out.
That will give a good start to debug your problem 
Specifically this will give us all info about your system:
inxi -Fxxc0z --no-host
You’ll need to install inxi first:
sudo pacman -S inxi
Also this will give you errors in journal, if there are some:
journalctl -p3 -xb
Video drivers most likely, we’ll need to see logs with commands above to give more details 
Here’s inxi -Fxx0z --no-host

did I post them correctly? Thanks in advance
Yep, usually it’s better to put logs in code tags like that:
```
code
```
But it’s fine, let’s see what you got here…
It’s PC, with i3 and Nvidia card, proprietary drivers. nothing unusual so far…
Show that file please
cat "/etc/X11/xorg.conf.d/20-nvidia.conf"

wow this one looks kinda messy 
Huh…Well anyway, according to that metamodes setup you shouldn’t have tearing / stuttering with i3 
@joekamprad @jonathon @BONK, ideas?
yeah it’s kinda weird…
after a fresh reboot = tons of tearing and stuttering…
once I logout and log back in, everything’s smooth and snappy
Perhaps that is the problem, but i’m not sure how to heal, need others:
What changes have you made to your picom.conf ?
absolutely nothing…
could be that compositor (picom) is the issue, you could try enable vsync (disabled per default)
Or try
exec --no-startup-id xcompmgr -c
and comment:
# exec --no-startup-id picom -cC
had little issue with -cC so switched to -f
Screentearing with NVIDIA’s proprietary drivers
Try this setting in
picom.conf:vsync = true;
Screen artifacts/screenshot issues
Try running Picom with:
–backend xrender
or add
backend = “xrender”;
to your
picom.conffile.See [5] for more information.
https://wiki.archlinux.org/index.php/Picom#Screentearing_with_NVIDIA’s_proprietary_drivers
-f, --fading Fade windows in/out when opening/closing and when opacity changes, unless --no-fading-openclose is used.
i know
tried this after testing your second suggestions but no luck 
tried all the suggestions but no success…
it’s just a minor annoyance so I guess I’ll just live with it 
thank you all for the input!
added those lines but to no avail…
it’s really weird cuz everything’s fine after i do a simple logout and loggin back in
Do you have a swap file?
