It can be demonstrated by slowly dragging a vertical scrollbar.

Comment 3 Miloslav Metelka 2011-12-05 09:43:25 UTC

This is regression due to issue 203118.
On Mac OSX using java.awt.geom.Area objects generates this problem so I've disabled that optimization (aggregation of multiple text fragments with the same foreground color into an Area object for a single TextLayout.draw() invocation). 
Still rest of the original patch should improve performance of the long lines well so the issue 203118 should remain is fixed state (QE is testing that right now).

Comment 4 Miloslav Metelka 2011-12-05 09:54:35 UTC

Confirmed by QE that the long lines are still ok after this patch.
