(tested by using the config file from #1497.)

I believe this is caused by own_window_argb_value being interpreted differently on Wayland vs. X11. Specifically, on X11, this only affects the window background, while on Wayland, this alpha value is used for all non-text drawing (because text uses the xftalpha setting).

I think we need to decide once and for all how to handle alpha in Conky: is it separate from colors, or included with them? We conflate ends and means in the current configuration scheme: own_window_transparent overrides own_window_argb_value, but should really be equivalent to own_window_argb_value = 0, except that it actually triggers a different implementation that can work in more X11 configurations. Meanwhile, color parsing does support reading alpha values, except for places where the parsed alpha is overridden by xftalpha or own_window_argb_value.

A workaround for now is to change own_window_argb_value to 255, but that does mean it's not really feasible to share configurations between X11 and Wayland, which isn't good.
