gamescope Forcing Intel GPU?

Hello, I Wanted To Compare My inbuilt Intel GPU With My Nvidia GPU But I Dont Think Theres A Way To Run GameScope On Intel GPU.

i get this error as well, only when running gamescope on drm (running nested has visual glitches and lag)

See #1215 and this commit.

The modifiers empty assertion is being worked on, but after that there are still some issues with Intel + embedded mode.

As for your issues with nested gamescope:

in terms of visual glitches, how severe is it for you? Is it complete color corruption? What version of vulkan-intel/mesa are you using currently?
As for the lag you were experiencing, try building gamescope from my forked branch: test_w_no_lut: https://github.com/sharkautarch/gamescope/tree/test_w_no_lut It has a collection of tweaks/edits that should reduce lag/stuttering on igpus

To build and install my forked branch of gamescope:

git clone https://github.com/sharkautarch/gamescope
cd gamescope
git checkout test_w_no_lut
git submodule update --init --recursive

trying with that just gives a sigsegv, logs:
