Description Shawn Liu CLA 2017-11-06 04:10:33 EST 
Control.redraw is too slow in macosx high sierra.

In my own Eclipse RCP application, I use FigureCanvas to show some contents. When refresh, FigureCanvas call redraw() or redraw(x, y, width, height, all) to update its figures. But this call cost too long, even if just redraw a samll rect area. (eg. need 350ms+ when redraw a small rect like (0, 0, 80, 50) in my mac, that's ok in Windows and old macosx version(10.12, macosx sierra)).

Please update SWT to adapt Macosx High Sierra, to make it perform better and useful.

Thankyou very much.
