Mouse cursor gets laggy after connecting an external display.

Hi, I'm running Arch on my Asus laptop, but everytime I connect an external display, the mouse cursor gets really laggy. I also noticed that it is more laggy over some windows than others (for example smooth over Dolphin and not smooth over Firefox)
It can't be a hardware issue because these are the specs:
Intel i7-10750H
RTX 2070 M
16 GB ram
1TB NVMe drive
Also, as I'm dual booting, the problem doesn't appear on Windows 10, everything works smooth there.
I'm using KDE Plasma 5.21.4 with X11 session (because I didn't find a way to make my Nvidia GPU work with Wayland and two displays)

Thanks in advance!

Something™ prbobably stalls the system and causes input event handling lags.
nvidia has massive issues w/ the 465 driver and certain output configurations, so try to use the 460xx packages (using nvidia-dkms)

I removed nvidia and installed nvidia-dkms package. It still works the same. I noticed that it is still the version 465xx of the driver. How do I go back with the version to 460xx?

nvidia-dkms of which version?

pacman -Qi nvidia-dkms

There's no benefit to just use the dkms version of 465xx, the plan is to revert to 460xx and the dkms package is what is going to help you itr.

This lengthy thread discusses the known issue and how to rever to 460xx, https://bbs.archlinux.org/viewtopic.php?id=265563

Unfortunately I didn't manage to downgrade the drivers. Package nvidia-460-dkms does not exist.
How can I downgrade it?
