I submitted
this bug report including a demo app that shows that an app with a virtualtreeview has the following issues:
1) toolbuttons becoming invisible until clicked (just click on the top toolbar to expose them)
2) TPageControl tabsheets misdrawn until clicked
3) TEdit looking very weird with black background until clicked
4) some captions/labels etc. are drawn upside down some places
To see all issues simply
- run project
- doubleclick window title bar (minimizes to dock)
- open from mac dock.

Dimitry was kind enough to write back it was a clipping problem in Cocoa implementation.

i understand clipping stuff is probably complicated... But my problem is I need a virtual treeview control since I may have up to a million items with 50 data columns... But still.. Is thee any LCL control I may be able to use instead of virtual treeview?
