The "master" branch on GitHub is indeed different from the latest
release version (that would be the "stable" branch, or the v3.7.0.0
tag), and includes plenty of improvements and bugfixes over the latest
official rlease, so some differences may be intentional, though I'd
indeed need to know more details in order to give you a more specific reply.

If you're worried about the quality of your build, you may want to
compare it to the latest semi-official development build of the master
branch, which can be found at https://github.com/c-lipka/povray/releases.

Also, Linux builds frequently use different mathematical precision than
Windows builds (and there may also be differences between the Windows
plain 32 bit builds on one hand, and the 32 bit SSE2 and 64 bit builds
on the other hand), which in some rare cases might produce noticeable
differences in the output.


That said, there is also a possibility that you've found a bug, and
therefore I do indeed want to know more about this.
