Bug description:
[Impact]
There's a shader bug in 22.2.x, fixed upstream in commit
https://gitlab.freedesktop.org/mesa/mesa/-/commit/7e68cf91d74e6bd9a88c2b52417451d9afec4782
but since 22.2.x is already EOL, we need to backport it.
[Test case]
Install update, check that the application from the submitter works.
[Where things could go wrong]
This is a oneliner that flips a bool, but it's hard to imagine use-cases
which would expect the old value.

I have a bug that occurs in Ubuntu 22.04's most up to date libmesa related
packages (=22.2.5-0ubuntu0.1~22.04.1) that was not there in =22.0.1-1ubuntu2.
It has since been solved in mesa's repo and pulled into debian's repo. I do not
know the proper way to request an updated version be made for Ubuntu. I've
manually installed many different versions of libmesa to test on my own that it
was working in an older version, is broken in this update, and was fixed again
in 22.3.4 and 22.3.5.
The one-line fix is implemented here in libmesa's repo:
https://gitlab.freedesktop.org/mesa/mesa/-/commit/7e68cf91d74e6bd9a88c2b52417451d9afec4782
Unfortunately I'm not using libmesa directly. I'm programming an
application using fox-toolkit which interfaces with libmesa behind the
scenes for me. I reported my issue to them first, and they stated it
appears to be in the mesa library, which is what ultimately led me
down the path to their repo, debian's repo, and here. Please let me
know if I'm in the right spot, and, if so, what my next step is to
properly report this.
