So again, a bit more with 1.1.15.
On a hunch, I've tried backbuffer again.
As opposed to fbo (which still produced just a black window now), it displays
nearly everything it should...except for the text.

The very first commit that breaks things is commit
889be9d447329994f009726d4e79a2fb3772e456.
It's not the one that makes text invisible, but it scales the glyphs into much
too large size. I suspect, that one of the later commits simply uses that wrong
size to move the glyphs outside their drawing boxes, making them invisible.
