Hey, I recognize that art! That's the Pepper & Carrot guy! iirc, that's a FOS webcomic (CC BY 4.0 license, artwork and transcripts available for each episode). We need more people like him: using FOSS to create FOS media and contributing to the community with write-ups and guides; what a mensch.

I haven't had many issues with wayland, but there are a few sticking points, and it's usually when you get into the weeds like this. Wayland is ready for mainstream release because all the software that gets the most use is taken care of already, but when it comes to niche edge-cases, it still has a long ways to go; and it will take a lot longer to "get there" all across the board, given how uncommon it is for the already relatively small amount of people doing the edge-case work to also either have time enough to walk devs through the issues or have enough coding knowledge to contribute to the software directly.
