If I had to guess I'd say it is, but it shouldn't be that hard to
write a test for that.

Sounds plausible. But that's something we have to fix anyway then,
since if it does. that means we potentially overwrite constant values
set with SetShaderConstant*.

Did you use dcl_ instructions by any chance? That's one of the things
that only really works with d3d9.

As for documentation, there's

not sure if that's what you're looking for though.

Either way, we should test d3d9 as well, since it's quite possible it
behaves the same for the 2 points you mentioned.
