None of the x11 sessions in any DE were as smooth video output-wise as the Wayland sessions I tried, especially with multiple monitors, they always had various problems and stutter.

That is why I switched to Wayland in the end.

They had 6 months of testing with release candidates, although you are not entirely wrong there are bound to be bugs still. Plus this release is almost entirely DB related refactoring, so you are not wrong about the maturity side either.

That’s just what you get when you fork a codebase with no care about code quality (hopefully after this it will be in a good place).

1. They have an experimental Wayland session already. It mostly works except for some pretty important stuff…I also haven’t seen development on it for a long while.
2. I think this is almost a 100% no.
3. I tried to implement that myself. Making them shorter than the screen is easy. Making them appear above the edge of the screen is hard, but not impossible - the code is in JavaScript and the logic is kind of disjoint across multiple files and stuff depends on panels being at the edge of the screen - I didn’t do it in the end because it was too much effort for something I didn’t want that much.
