Help debugging weird font/display issue

I recently found the display on my software player (SoftSqueeze) has become completely garbled when rendered in small sizes. I know SoftSqueeze isn't supported any more but originally it worked fine, and apart from this, still continues to work like a charm in all other areas. I'd really like to continue using it. And I've spent many hours already trying to get to the bottom of what the problem is.

I've confirmed it's not the missing Font::FreeType problem others have reported with display issues. The LMS Graphics directory seems intact with no font files missing or altered. Log file doesn't report any errors. My hunch is that this problem could have crept in when I upgraded my Mac OS from Mavericks to El Capitan - a long time ago. Differences in the Perl packages bundled with the OS? The LMS server is v7.9.0 running on OS X 10.11.2 - EN - utf8, x86_64 arch, perl 5.18.2. The player is showing up in LMS as "Player Model: SoftSqueeze, Firmware: 2"

Any pointers would be appreciated. I am not even sure whether I should be investigating the player side (SoftSqueeze) or this is an LMS server issue. Thanks.

PS: FWIW, when I go to LMS settings and select the player display options, Fonts, the only choices I see are ones like full_n, standard_n, high, light, threeline etc. which I think are all bitmapped fonts (.bmp files). Could that be the issue?
