Wayland seems ready to me but the main problem that many programs are not configured / compiled to support it. Why is that? I know it’s not easy as “Wayland support? Yes” (but in many cases adding a flag is enough but maybe it’s not a perfect support). What am I missing? Even Blender says if it fails to use Wayland it will use X11.
When Wayland is detected, it is the preferred system, otherwise X11 will be used
Also XWayland has many limitations as X11 does.
It’s true what you write, but it’s not related to Wayland/X11.
But this is the reason CAD software can’t use multiple cpu cores for geometry calculations. The next calculation needs the result of the previous one, it can’t be parallelized.
