[R0b0t1]

Hello again, very sorry for the three posts. It is the case I am not very
smart. Please excuse my poor reading comprehension.

components (like a SynEdit) may be drawn with colors not taken from the
toolkit's configuration.

I realize now you were asking to disable theming in Lazarus. That answer is
related to the contents of my other posts, but for GTK you may use the
environment variable GTK_THEME:
https://developer.gnome.org/gtk3/stable/gtk-running.html.

GTK_THEME=theme:variant

If you have some time I would invite you to comment on the forum as it is
more active. It would be nice to see pictures of the interface quirks you
take exception to.

Cheers,
