Hi,
by using GNUstep and some apps a bit I can confirm the "mixed"
performance of the new backend, something is better, something
definitively worse.
On my computer at home (FreeBSD/GeForce local X display) I notice
visible flickering when watching images full-screen using LaternaMagica
and "scale-to-fit" selected. When I display the next image, I clearly
see the new image shown correctly, then a black flicker, then re-displayed.
Doing the same on my Laptop (NetBSD/i915 local X display) is totally
fine. I even exported the display to another host and it displays
without flickering and reasonably fast. Very strange!
Window-Flickering while resizing is however visible everywhere. Even
without solid resizing, I can clearly see that when dragging and
re-sizing the window, the only redraw at the final size blanks out white
and redraws. Clarly, using live-resizing and repeating this many times
will flicker a lot.
