Iconstrip randomly contains missing pixel line

[GWRon]

Sometimes builds of MaxIDE contain a missing-pixel stripe:

Rebuilding MaxIDE fixes the issue - or not. Seems kind of "random". But once the .exe is built, the problem stays, so it is a building-issue, not something during execution (except the incbinned data is corrupted).
The white stripe seems to be on the same position each time (did not verify that - but it always was in the "upper half" at least).

Either MaxGUI has a bug - or code in MaxGUI has one).
Also I only saw this on Windows builds for now.
