« on: September 26, 2015, 11:18:50 am »
From this thread here
http://forum.lazarus.freepascal.org/index.php/topic,12172.msg188486.html
(see page 2 and 3)

a bug in Carbon Widgetset was found as reason for problem in virtual treeview:
"Device Context Origin is not respected in BitBlt under OSX"

Just posting here incase there are "Carbon" people here who knows their way around Lazarus Carbon widget set.
