Shadow bug in underground belt

[MrAsadli]

When items pass through underground belts as shown in the video, the shadow disappears sometimes

Could you provide a log file and a save file where this issue can be seen?

Since i cannot reproduce this issue easily, i need the log file to know what are your graphics settings in case any of them would be relevant for this, and a save file is needed because some of the graphics issues from the past were position dependent.
