Slow graphics when using HiDPI

I have recently bought myself a Huawei Matebook X Pro 2018, and got Monterey working on it.
I have one issue, the built-in monitor's native resolution is 3000x2000, but that seems to make everything sluggish. Changing it to 1500x1000 seems to fix the issue. Should the iGPU be this bad?

Specs:
i7-8550u
Intel UHD 620
16GB DDR4
