ScummVM Final Version (first screenshot): ScummVM 0.8.0 (Oct 29 2005 16:14:12) Features compiled in: Vorbis FLAC MP3 zLib MPEG2
ScummVM Snapshot Version (second screenshot): ScummVM 0.8.0CVS (Jun 25 2005 14:34:12) Features compiled in: Vorbis FLAC MP3 zLib MPEG2
The hq2x/hq3x filters in the final 0.8.0 MacOSX version no longer work properly. Attached are two screenshot showing Beneath A Steel Sky (same results occur on other games too) with hq2x filter (first screenshot: final version, second screenshot: snapshot). The hq3x filter yields similar results.

Indeed, I can reproduce the problem -- but I can reproduce it with all my builds. I have no idea who built that snapshot nor on which system, so I can only guess that it's a matter of the compiler; or of optimization; or of altivec support... Will investigate.

Disabling the altivec code seems to solve the issue for me. Maybe a matter of GCC 3.x vs 4.x.

I'll upload a binary with disabled Altivec now, to work around the bug. I'll find a proper fix once i have some more time.
Thanks for the report.

Things work fine with GCC 3.3, too, so a compiler bug (or a semantic change to the altivec C extension) seems more likely again.
