Yes this is a good workaround for now. I got it down to 0,0,40 and it

I render a simple image in this case it looks like burshed aluminum and
then render some text. If the text is too close to black I get nothing.
I am recompiling to use Freetype2 to see if that fixes the issue.

If it is on then that is good enough for me. I looked good on my screen
but I am used to seeing that option in the config.
