Yes, an easy ‘fix’ for this is to set the system to use the dGPU.
But this can also be avoided through some extra elbow grease.

Since you’re using an external monitor, you probably want to follow this like I do: NVIDIA Optimus - ArchWiki
I have three external monitors connected to my hybrid Intel + NVIDIA laptop: DP, HDMI & Thunderbolt 4. The former two are connected to the discrete NVIDIA card and the latter are connected to the integrated Intel GPU.
I created a split package for all use cases based on the aformentioned Arch wiki article. You can try it out if you’d like by following my README , install it and reboot a…
