Very fast 2D graphics in Lucid!

[ernstp]

so I guess it was indeed the GTK work: https://edge.launchpad.net/ubuntu/lu....19.5-1ubuntu3

I see, very nice! So that's what makes Compiz resizing so smooth. Only works with some window-themes.

But that doesn't explain why my gtkperf score improved from 12 to 5!
However...

[ernstp]

As of yesterday, or day before, I'm getting a huge regression in rendering speed on my desktop (Lucid, xorg-edgers, ATI HD3650)... Both 2D and 3D...
GTKPerf dropped from 5.00 (was less than 4 weeks ago) to 8+...

...mine also dropped from 5 to 8+ today! Can't be that many packages, should be possible to find with some free time at hand...

[ernstp]

If I start from a livecd dated 20100215.1 I still get 5 secs in gtkperf. However it doesn't go down even if I upgrade all packages and restart X.

Xserver 1.8 should further improve the EXA performance (not in Lucid, though).

Ah, that's probably a change in GTK so nothing to do with the radeon drivers:

I do not know what is the reason, but I'm back to less than 5 in GTKPref... I love it. Who ever fixed it, good job.

It's an update gtk package where the bug I linked above has been fixed.

GTK+ 2.18 vs. 2.20

This very fast graphics is said to come from client side windows. But this was introduced already in 2.18. So there are two options:

1. client side windows where somehow disabled in karmic's version of gtk+-2.18
2. There where performance improvements introduced during the development of gtk+-2.20

Anybody?

client side windows and client side decorations are two different things.
c-s-decorations is new in Lucid.
But there must be other work in Lucid also, both in Xorg and gtk.

I know. The first one is to prevent creating a X window for every widget and to make the code more portable, the second one is for drawing -- well -- decorations on the client side (something like chromium does).
