artifacts on screen with Nvidia drivers when using an ultrawide monitor (self.linux_gaming)

Hey everyone,

I have a gaming laptop with fedora installed and in general have no problems with it. However I would like to play some games on it from Steam.

So I installed the Nvidia drivers and when the laptop is not using an external monitor it's great, the games performance are 10/10.

However I most often use my laptop plugged into an ultrawide monitor and when I do that with the Nvidia driver active all sorts of strangle artifacts show up on the screen and the edges go blue and shudder, this slowly gets worse over the course of about 15 minutes until I cannot use the laptop at all and need to reboot.

Using the built in drivers the ultrawide monitor is completely fine, but games run very poorly.

Does any one have any experience with this, and any idea if there's something I can do to correct it?

This. I had weird refresh rates showing up for my older 4K TV until I got a HDMI 2.1 cable, especially KDE Plasma... topped out at 30Hz for some reason. Got a "Highwings" 8K cable which was cheap but seems decent quality. Don't get excess length if you don't need it.
