The QT_QPA_PLATFORMTHEME environment variable is special to Lumina and will 
automatically get overwritten when the desktop starts up.

Lumina will automatically change that variable to "lthemeengine" (Lumina 
theme engine), which is a custom fork of the qt5ct theme engine with 
additional support/features specifically for desktop/application theming 
(such as more color palette support, ability to scan system-installed 
palette and theme files for availability, things of that nature).

TLDR: Don't use qt5ct with Lumina. Just make your changes in the Lumina 
theme engine utility instead (nearly identical to qt5ct and behaves the 
same way).
