I had the same issues as you, but managed to fix them by installing the GFX drivers for my laptop from Dell's website. The ones I had that I got via Intel's website always resulted in a crash.
It could be worth a shot to try that out if you are in the same boat I was.

Hey there fellow Dell XPS user.
I had the same issues as you, but managed to fix them by installing the GFX drivers for my laptop from Dell's website. The ones I had that I got via Intel's website always resulted in a crash.
It could be worth a shot to try that out if you are in the same boat I was.
Good luck!
