Besides seeing the focus ring problem, too, I have one more effect to contribute: I gave a view inside a split view the wantsLayer attribute. This view in turn contains a table view, which is resized together with its container view. Now while resizing the pane with the mouse, the table view starts to flicker during redraw. That is, it draws its background, makes that visible, then draws the content text for each move of the mouse.
The split view is custom made, so it is possible that the problem does not happen with NSSplitView, but I doubt it. All I do is calling [pane setFrame].
Lets hope for 10.5.x (x > 1)
Best
Kai
