Well, I just tested it again, and as mentioned before, playing with the previous version of Spectra seems to resolve the issue, so there's definitely something different in the current version which may be triggering it. Now, the what and why of it is beyond me, but using the previous version of Spectra solves the issue. Not sure if that gives you any idea as to where to look, but it's really not a huge deal at all since it only seems to affect the title screen.
