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.
Until recently, Wayland development was rather slow, especially in the areas where more specialized software run into issues that force them to stick with X11. Since Wayland does a lot less than X11 and is more componetized across multiple libraries designed to be swappable, some of these areas simply do not have solutions. Yet.
And, as always with FOSS, funding is a big part of the problem. The recent funding boosts the GNOME foundation received have also led to some increased funding for work on Wayland and friends. In particular, accessibility has been almost nonexistent on Wayland, so that also means that if an app wants to ensure certain levels of accessibility, they can’t switch to Wayland. GNOME’s Newton effort is still very alpha, but promising.
While big apps like blender and krita get good funding, they can’t necessarily solve the problem themselves by throwing money at it, either. But the more funding Wayland gets to fill in the feature-gaps and ease adoption, the sooner we’ll be able to move away from xwayland as a fallback.
Wayland and its whole implementation process certinally aren’t without fault. There’s a lot of really justified anger and frustration all around. Even so, staying on X11 isnt a solution.
