[2.0.4] Pilot side window glass appearance

[daemotron]

Observed in the 5 blade glass variant, version 2.0.4: from outside, the glass looks as if it weren't there:

When looking from a different angle, it's obvious the glass object must be there however:

To me it appears as if there's something going on with the tinting or reflection of the glass, but it could also simply be my dreadful eyesight ^^
