X11, Window Managers Some Trolltech programmers are doing some optimization work in the RENDER extension. RENDER has been used with COMPOSITE to make "transparency" and "shadow" effects, and its slowness has stopped it from being widely adopted. Hopefully, this optimization work will make things better, although it's not clear in the email if this addresses the "XAA sucks, someone needs to take KAA to" problem which is often said to be the real problem of render slowness. RENDER is also often used to do more things, like AA fonts, so this will be good for X desktop in general.

Re: I actually donated some routines ...

are these routines from imlib2?
if render improves, would imlib2 start using render?

imlib2's blending is really great, it's astounding to see imlib blend with an alpha gradient, 30 fps, and have a really low cpu usage:
