I've seen that too, you can reference:
rdar://11852080
Overlapping NSViews draw in wrong order when layer hosting/backing is involved
Duplicate/10348980
and:
rdar://11805856
'View Programming Guide' doc incorrect about overlapping views
My workaround is:
// For some reason the views don't draw in the right order unless we
give them a little kick. <rdar://11852080>
id subviewsCache = [[[self stageHolderView1] subviews] copy];
[[self stageHolderView1] setSubviews:subviewsCache];
The bug dates from 10.7 and will presumably never be fixed, like most
everything in Radar. Sorry, can't help it. :)
Cheers,
