Problems - to say the least - with LSS16 images have been reported 
several times since the release of version 5. Unfortunately, there has 
been no improvement in the code that would solve these. That's under 

Under UEFI, not only that LSS16 images are not being displayed, but all 
sorts of inconsistencies regarding the boot screen(s) and the boot 
prompt have been reported too. Most of the rendering/displaying 
problems have not been resolved.

At any rate, to anyone attempting to use/test Syslinux (in any of its 
variants) from version 6+, I would suggest at least version 6.04-pre1, 
or, even better, the current binary packages from Debian Testing, over 
the possibility of using/testing 6.03.
