Version: (using KDE 4.2.85) Installed from: Unlisted Binary Package This is actually tough to explain. When I try to activate the blur plugin, kwin tells me that It couldn't be activated. I guess my hardware doesn't support it. When I logout though, my desktop blurs, which led me to think that maybe the blur effect is implemented in some other way, that a greater range of hardware can support. Maybe an option could be added to the blur plugin to choose the method to use. I'll attach a screenshot of my blurred desktop.

I forgot to tell you that I'm using an Intel 945 with the intel driver.
The new logout blur is actualy a result of trying to get a better blur effect. Unfortunately the technique used in logout blur cannot be used for the blur effect. The performance is too bad.
"Yet", I hope. =) Thank you for the response.
The new blur effect in 4.5 supports ARB shaders, so more hardware should support it than the old one. Adding a mipmap LoD fallback will results in bad looking visual appearance so we should not consider it.
*** Bug 271681 has been marked as a duplicate of this bug. ***
This bug needs to be reopened. The blur effect is now perhaps the greatest factor that affects performance. As it is now, my system, and many others, are unusable on two-screen configurations. The current blur effect cripples: Resizing, maximizing, minimizing, opening or closing windows; changing focus between one window and another, switching desktops and almost everything that has to do with window management. OK, mipmap LoD looks a bit blockier that the silk smooth gaussian blur. So what? Martin, do you really think that such a trivial difference is much more important than usability? Blur effect makes many systems unusable (especially older ones). I'd rather have the option to choose a worse looking alternative to having no blur at all! I'm not ordering anyone to work on anything, I just don't understand why this problem is not acknowledged. People cannot use their system as it is now. How is this not a problem?
(In reply to comment #7) > This bug needs to be reopened. This is a feature request and not a "bug". Therefore it is quite correct that it is set to wontfix as nobody of the core development team is going to implement this feature and it is unlikely that we would accept patches for it. So it is the most honest thing to mark the feature request as wontfix as, we won't implement it. Keeping it open and not doing anything would give you and others the wrong assumption that we work on it. > Blur effect makes many systems unusable (especially older ones). With 4.7 there are more safety guards to not activate the effect on systems not capable to run it and there have been optimizations. > I'm not ordering anyone to work on anything, I just don't understand why this > problem is not acknowledged.
