Is it something specific to a particular model or combination of those? Because I run a laptop with amd integrated GPU and discrete nvidia GPU (not that rare, actually) and Wayland works flawlessly. Games use xwayland without any issues when necessary.
I used to have my reservations a year or so ago, but Wayland has grown in leaps and bounds over the last couple of years. It is much more ready now.












Oh, my bad. Misread it the other way around. Disregard the comment then. That said. I disagree with the other commenter. Such a combination of GPUs is not rare at all. It was even recommended frequently to PC builders about 5+ years ago.
