Hi again, > > I think, the blitting is broken again, because width=450,height=426 > > means that the whole table should be repainted.
Another part of the problem is the following stacktrace that I get when
intercepting repaint() in JTable (below). You can see that the painting
of the cells goes into CellRendererPane.paintComponent() which must call
setBounds(), which in turn calls repaint() somewhere which ends up
repainting the whole table. Stupid. This was caused by me making the
CellRendererPane a child of JTable, as it is in Sun. The mistake here is
to have the CellRendererPane set to visible. The attached patch fixes
this (the CellRendererPane is invisible in Sun's impl too) and blitting
is smooth again.
