If the resolution is set above 640x480 there are bright (or white?) fine
lines in the background pattern of e.g. the main menu. Also in the game,
in the scenario, these gaps can be seen sometimes. Here they appear and
disappear on different positions as you move Lara. The gaps seem always
be on the boundaries of the filled shapes.
In the attached screenshot there are two such gaps. One in the upper
right part of the black entry to the building. The other in the upper part of
the left pillar of the entry (make sure that you look at the picture at 100%
magnification to see this one).
This problem appeared already before MacGlide v. 0.11 but was not
present in the early versions as far as I remember.
OS 10.4 and 10.3 Classic, Tomb Raider II 1.0.3(g), MacGlide 0.11,
on several Mac's.
