[Message part 1 (text/plain, inline)]

I think you're right! Changing mesa from a regular input to a
propogated one seems to have fixed all the issues for SDL. I no longer
need patches 3-6. See below for what we can use instead. Can I push the
patches now?

* gnu/packages/sdl.scm (sdl)[propogated-inputs]: Add mesa.
[inputs]: Remove mesa.
