Describe the bug

Horrible Lag when doing anything, even moving the mouse on monitors plugged into my dGPU. I believe this happened after upgrading to the latest version 595.58.03, I only just started noticing this yesterday, but wasn't using my monitors at my desk yesterday. I couldn't get any other nvidia driver versions installed. Tried to downgrade but it didn't work. Pacman and yay dont give me the option to install the proprietary driver just the nvidia-dkms package at this version.

Sometimes its fine for a few seconds but then it will go back to lagging horribly. Even completely locking up the mouse for like 20 seconds or so.

To Reproduce

• Use a gaming laptop with an nvidia dGPU, preferably same GPU, the 3080 laptop edition.
• Install latest nvidia-dkms drivers
• Try to do anything, move the mouse, launch an application, it will lag horribly.

More Info

If anything I can improve on on detailing or information I can provide let me know. Not sure why I couldn't find the default nvidia package from pacman and yay, it would let me install it before. If I could get assistance on that if it will help produce logs or investigate the issue, that would be great. I need my monitors to work badly

Update for what it's worth: I reinstalled arch to a fresh install and am still having the same issue, leading me to be rather certain it's gotta be something to do with these drivers

I had some similar issue, when I upgraded from 590 to 595.58.03 (nvidia-open-dkms) everything was super slow, even the mouse pointer was laggy, my kwin-wayland was using 90% of CPU.

moving my mouse/focus to my laptop screen, things went back to normal, but as soon as I moved my mouse pointer and switched focus to my external display, any action was laggy.

I reverted back to driver 590 and things went good for another few days, then this morning I gave it another shot, but this time I installed nvidia-open and not nvidia-open-dkms since I'm using a standard kernel, and now everything is working fine.

Update: I was finally able to successfully revert to version 590.48.01. And it now works. It's definitely a bug with this driver.

I also noticed this was only a bug on KDE Plasma's desktop environment. Since reverting the drivers without downgrading plasma fixes the issue, I believe its still likely an issue specific to these drivers instead of something plasma would have to fix. I tried gnome and I did not experience this issue. Maybe @Cae2 can provide insight to what desktop environment they were using as well.
