Am I correct that Qt now provides a Wayland QPA and that users on Linux can now
decide, in principle "on the fly" which displaying protocol a newly started
application is going to use, presumably with a platform-wide default either
hardwired into Qt or defined in some settings file?
If so, how does that work out with KF5 applications that get started by others?
Say, a user with a Wayland-based desktop logs in over ssh+X11 and wants to run
kate remotely with `kate -platform xcb`. A new session dbus will be started,
and during Kate's start-up sequence kdeinit5 will start which will then start
I just tried this on OS X (I have a working XCB QPA on my system, plus a
patched dbus that works without launchd). kdeinit5 starts up fine because it's
not a GUI app (I think), but klauncher is. It doesn't inherit the `-platform
xcb` arguments, and thus fails because the Cocoa QPA only works locally.
Mostly asking out of curiosity, though I would of course appreciate it if on
occasion I could use applications like Kate remotely.
