[Kstars-devel] KDE/kdeedu/kstars/kstars

[Jason Harris]

SVN commit 503551 by harris:

Turn off antialiasing when the display is being slewed.  This makes the 
display much more responsive (but it still seems a little bit slower 
than under 3.x).  Optimization work is definitely on the back 
burner, we can worry about speed when everything is stable and working.
