@roninbadger Hi I don’t run Plasma or X11, so could be something up there…
I use Nvidia as an offload device (coupled with an Arc A380) so you can set the Mesa device via a /etc/environment file containing in your case MESA_VK_DEVICE_SELECT="8086:e20b"
Edit: That’s assuming libvulkan_intel is installed?
I’d also suggest Wayland as there has been a lot of work on the Xe driver…
