Wayland compositors will happily use gpu 3d engine, if it is available. Otherwise, they will do their job with Mesa's software rendering.
They also accept dma-buf handles from clients, so if other software on the system does use gpu, the compositor has somehow to do its composition, and zero-copy if possible.
My laptop isn't dying, dude. It works perfectly in Windows 11 and X11, including running the latest games.

Fair enough. I only suggested it because it turned out to be the root cause the last time my video flaked that badly. Heat sink had failed.
The symptoms you describe almost sound like a dying 3D graphics card (or 3D graphics card with misconfigured drivers). I wonder if Wayland is requiring the 3D layer to do its compositing and other window engines don't?
