The problematic nature of the Linux desktop is due to the inability to have a standardised and integrated desktop experience but instead its community goes for an ecosystem of having alternatives of alternative subsystems competing with themselves rather than improving upon each other. I don't want to spend hours googling and customising different settings all for it to suddenly break and then reseting the whole OS to fix it.

There is only one version of macOS and Windows to test against but thousands of Linux distros that behave differently with many DEs, Window Managers, audio subsystems, packaging formats and the list goes on. As a software developer I can imagine that it is harder to test a GUI app on several Linux distros than it is on macOS and Windows since tracking down the fault of the issue may involve switch/upgrading either GNOME, KDE, GTK, Wayland, X11, libDRM or even Linux itself. This is just too much work.

The closest answer to having a 'consistent Linux desktop' is ChromeOS.
