I'm checking the link you provided but it doesn't look like my issues.
I have only highlighted visible changes (no bugfixes). The engine is a modified ioquake3 engine, so bug and bugfixes are inherited from there. ioqauke3 is currently stabilizing to get a stable 1.36.
The current test binary have several fixes to the renderer (from ioquake3) so your problem may have been solved.

I don't think the Legacy will be updated (apart from protocol/master server changes). They are already based on the latest ioquake3 with the old input code.
