I had a similar problem, and it didn't involve anything with the dedicated GPU.
First, run `kinfocenter` from the terminal.
If the output includes something like:
"GPU count mismatch (from vulkan). Are you maybe missing vulkan drivers? 1 2"
Then (seeing you have an Intel integrated GPU), install `vulkan-intel` and
check if the problem persists
