With Plasma 6.3.2 changing color scheme (light to dark) stop working for GTK apps. Always when i switch to dark all GTK apps stay light. I've wait with report to release new KDE Gear (usually it solving some problems after new plasma version release) but it not help. There is still cursor problem for GTK, some apps have normal cursor some very big, some smaller.
