Sorry, I’m not so well educated in KDE Does this glow mean that blue “frame” around the active window? I’m even a bit confused Hope my english is understandable

Of course I will keep the compability with the old world. That is there will either be a new backend or the OpenGL backend is changed in a way that it does not use the old code when shaders are used. Currently I’m working on the second approach. But I don’t know yet if that will work as for OpenGL ES we have to #ifdef away the old world.

For new stuff in effects using OpenGL 3 functionality it will be the same as currently with OpenGL 2 – additional features will only be available if the hardware supports it or an optimized version is used. So I want to implement the Magic Lamp effect with a geometry shader and of course I can keep the old code.

When we’re talking about OpenGL ES/3, I’m missing some information: Will you keep compatibility with graphics drivers that do not support the new, shiny OpenGL 3 features?

You could wrap all required strings in Q_UNUSED(I18N_NOOP(”Foobar”)). Of course this requires that a) you know all strings and b) any actions comply with the hard feature freeze on Wednesday. (I think that b) is harder.)

Great, that one feature will be enough for me to upgrade to 4.4 when it’s out (not that I wouldn’t anyway)

I’ve tried numerous times installing nitrogen, but either somethings wrong with kubuntu packaging or I just don’t have the fu. Or both.

Btw, you guys are doing a great job with the kwin effects though, they look smooth

Oh, and who do I talk to if I want to have the “transparent cube” effect always on, like compiz lets you?

Qt3D won’t be available till Qt 4.7. It would provide some advantages. But currently it’s not yet an option. But my new implementation uses some of the new possibilities in Qt 4.6 like QVector3D.

Other comments are talking about blur… I’m most interested in opengl es/3
I think you’re right to not include your work on 4.4, regression on a window manager could ruin the whole image of kde in reviews
I’m quite impressed that “after spending some hours hacking ” you already had a basic implementation… For me this means that a) you are very skilled, or b) that kwin code base is ultra clean (maybe both who knows )

Anyway, good luck for the rest !

Why don’t you use Qt3d? I know it is just coming, but then it will run on Maemo6 and everywhere directly without duplicate functionality between Qt and KWin.

It’s a new feature in KDE 4.4 and can be turned off in the Oxygen configuration interface.

If you are using KDE 4.3 you can install Nitrogen from kde-look. It supports switching off the glow as well.

I’ve looked for it, but no I didn’t find it

I’m sorry that my comment came off a bit more harsh than I meant to – to me disabling glow would be a killer feature, not a showstopper

But please let me know where the glow can be turned off!
