My computer has dual video cards.
Hi @LeviSpektrum,
Have you tried another screen? Even if only temporary? Or that screen on a PC that you know works? (That might be difficult, because it sounds like a laptop.)
It’s not screen, it’s probably iGPU. I have same thing happening to me occasionally – on IvyBridge. Or maybe it’s faulty cable.
Yes, unfortunately I’m using a laptop 
so I didn’t have a chance to try it on another screen. I think it’s the intel driver but I didn’t manage to install another intel driver.
Then I suspect you’ll have to test another screen. This will allow you to test the cable which could be it, as @zbe stated:
There is only one driver per graphics card available, so you probably won’t be able to easily change…
Since it shows up on a screenshot it can’t be the screen or a cable, as long as the screenshot is taken using software
OK, that is true…I’m all out of other ideas, though…
what kernel, gpu-driver etc ? post the output of

okay, you’re at the internal intel-gpu. i would recommend to switch to nvidia.
a nice tool is envycontrol. install it with
pamac install envycontrol
run
sudo envycontrol --switch nvidia
reboot and post the output of
echo $XDG_SESSION_TYPE && glxinfo | grep server
after reboot
I had already tried switching to a secondary video card, but this time the window maximization and minimization animations were stuttering and my fan was spinning all the time. But I used optimus-manager to switch to the secondary gpu, does the program I used make a difference?
if you use optimus-manager then you’ll have to edit the configs as described here
https://github.com/Askannz/optimus-manager
what is the actual state of
echo $XDG_SESSION_TYPE && glxinfo | grep server
Yes, I followed the instructions here to install optimus manager. Now I’ll try to switch to nvidia using envycontrol. By the way, my problem disappeared when I ran firefox using prime-run. I guess intel’s open source drivers don’t work very well on my machine.
it’s the less performance of the cpu that is additional reduced with the actual setting of the scaling governor. switch to performace-governor
https://wiki.archlinux.org/title/Scaling_governor
if you use envycontrol don’t miss to disable and mask optimus-manager
sudo systemctl stop optimus-manager && sudo systemctl disable optimus-manager && sudo systemctl mask optimus-manager
if everything works well remove optimus manager complete

After resetting and uninstalling optimus manager, I installed envycontrol and switched to nvidia. Unfortunately, just like with optimus-manager, the window maximization and minimization animations stutter and I have screen tearing problems. I think the only solution is to run kde with intel and firefox with prime-run with nvidia.
please use the performance-governor and test this before. i’m very convinced running this cpu@1200MHz is the reason for your lagging-problem in the end
cpupower frequency-set -g governor
I need to use this code, right? And what mode is this setting in by default? I’m asking to undo the setting if things go bad. I’m a little new to linux 
there’s nothing going bad.
you can always switch between the governors you’ll find with
cpupower frequency-info
usually they are performance, schedutil, powersafe etc…
keep in mind that these changes just temporarily and are set to default after reboot. check the link from archwiki and dig into setting up governor-scaling. you’ll find a lot in the net.
use
sudo cpupower frequency-set -g performance
