KDE The KDE team has released KDE 4.3. This release comes packed with improvements and bug fixes - in fact, over the last six months, 10000 bugs were squashed, 2000 feature requests handled, and 63000 changes were checked in by 700 people. We've already talked about this new release in quite some detail last week, but let's take a look at the most important new features anyway.

So why can I resize Qt3, GTK+, Motif, etc. applications with little to no delay, even with a compositing manager running, on the same machine with the same driver settings, but Qt4 apps can't handle it?

I should file a bug, to be sure, but the problem is not the graphics drivers and it's time the KDE4 folks stop pinning the problem on the graphics drivers and instead own up to the fact that their software is SLOW.

Qt4 uses XRender much more aggressively. Funny though how NVIDIA fixed the very bad 2D performance with Qt/KDE4 in the 180.x series, people said exactly the same thing.

While I'm at it, NVIDIA fixed OpenGL crashes which affected Plasma and memory leaks in their driver. Have a guess who got blamed for that too?

It's time you jumping to conclusions you are not qualified to make. Do some research -- dive into some code, from kwin down to the X11 driver and then come back with a thorough analysis. You then will have helped a lot of people get informed and will have gained some respect. But right now, you're just spouting nonsense.

I don't need to look into the code and do a thorough reductionist analysis when the behavior is crystal clear: everything but Qt4 is slow on my system. If *everything* was slow, sure, blame the drivers. However, I find it very hard to believe it is just the drivers' fault if only one toolkit ever seems to have a problem. And if it is the drivers' fault, it's because the toolkit is making use of edge cases which the other toolkits can clearly get by without using and Qt4 should do the same. Again, don't need to look at code to know the correct answer here.

It should not take noticeable amounts of time to redraw a section of a double-buffered window during an exposure event. I don't need to look at code to know that that is bad behavior on the part of the toolkit.

The problem with doing this is that the KDE4 software is not slow.

KDE4 absolutely flies on systems where the graphics stack works properly. Fastest desktop there is.

And how do I get to such a system? What parts? What drivers? I'm genuinely interested.

I think that will be fixed on Qt 4.6
