When i add a theme with gtk-3.0/ folder and gtk.css in it (MyTheme1) select it with lxa, hit apply button, i see changes in e.g. gnome-terminal (which is linked against gtk3).
Then i edited the gtk.css file, changed the color somewhere, restarted lxa, reloaded a different theme, applied it, then selected MyTheme1 again, apply, i don't see any changes.
Renameing the theme dir from MyTheme1 to MyTheme2, applying MyTheme2 works though.
Renameing it back to MyTheme1, applying, changes it back to the old color.
Seems like it is cached somewhere?
Changes to gtk-2.0/ files work immediately after changeing...
