I think that given how frequently this argument is brought up (and it is of course true about it not being completely there yet) so this is just my opinion on the situation (and I am not a dev so I am fine with being wrong and corrected). It is kind of needed for more projects/distros to start actively using it. As a lot of the stuff kind of needs the band-aid ripped off to start forcing it to get there faster at this point. Otherwise it just keeps being held back as people on the coding end of things will keep focusing on X11 issues instead of getting things ready for Wayland.

Kind of like the conundrum of mobile OSes that aren't Android or iOS. It is hard to get people/companies to even try the new OS because the lack of apps (specifically the most common ones used by the most people). But app devs don't want to spend time re-building or starting new apps for an OS that isn't being used (or on devices people are buying). So at a certain point it needs both sides to interact and make progress. The OS needs the apps more at this point, and getting feedback and data from those devs makes it known where things are and aren't working. But it is also true the devs for the apps might end up finding out the OS is actually easier to work with compared to what they have been doing/dealing with on Android/iOS.

Getting a replacement for X11 has been needed for a long time as the OSes and features keep needing something new to better work for how computers have advanced. And it isn't something that many devs would want to take on given how easy it is to just use what is already known. Since Wayland has finally gotten to the point it is now, it is time for more devs to start learning/moving to the new thing to get attention to the stuff that they need. The hardest part is this in between period for users as it can and will cause random issues (like the ones you have seen). Stability is important, but Linux is great because there will always be distros and projects that keeping the old thing running well is the main objective. So we are in some great times for the new to be pushed hard so it can become the stable future needed.
