mikecomputing, that does not make sense. The entire point of using a toolkit such as GTK is so the application does not need to concern itself with the specifics of the display server.

i mean, Qt apps run on native win32 for freaks sake. If the binary format matches and no extreme UI weirdness has been done it should even be possible to just link against qt5 build for wayland vs link against qt5 built for Mir on a different system.
The current problems with 'porting' apps between X and wayland has more to do with the unfinished state of the wayland ecosystem, and how much x11-specific functionality crept into gtk+ and others

mrsellout pointing out the benefits of a robust GPLvn community without the interference of a Contributor agreement was a stronger point that above FUD.

Honestly X11 isnt even functionally broken on mobile hardware or desktop, I cannot think of even one single instance as a user in the last 8 years where I was like "OH GOD, not this silly X11 problem AGAIN!"

It's entirely developers (toolkit, driver, and X devs really) who are just tired of the non-stop hoop jumping required to work around the obsolete 1980's paradigm.

(although I have been using xpra for a while now, when needing single-window remote apps - so that may be part of it)
