I now use blur plugin thanx to window matching feature, thanx David ;) I have some bugs: http://hibbert.univ-lille3.fr/~cbellegarde/blur_4xbilinear_bug.png Here, i have some artefacts bugs with 4xbilinear. This blur mode is fast! May be a Nvidia drivers bug... http://hibbert.univ-lille3.fr/%7Ecbellegarde/blur_gaussian_fast.png Here, an amarok big window with just desktop, moving window is fast. http://hibbert.univ-lille3.fr/~cbellegarde/blur_gaussian_slow.png Here same amarok window with a fullscreen window under it (basket already have blur enabled), moving amarok is slow. Don't know really why it's slow... Maybe amarok window blur basket window that already blur desktop window. This may explain the slowdown... I'm really not sure :( Cedric
Le mardi 27 f?vrier 2007, Bellegarde Cedric a ?crit?:> I now use blur plugin thanx to window matching feature, thanx David ;)Just find another thing... Blur alpha effect is present for every alpha effect in compiz: fade, minimize, scale... For scale, it make sense to have blur under scaled windows... But for animations (minmize, fade, ...), does we need to have blur effect in animations? It should make sense to disable blur in animations... Cedric

The blurring behind the amarok window depends on the blurring behind the window below. We're not blurring windows here, we're blurring whatever is rendered behind the windows, which is a lot harder than just blurring a window or texture. - David

Please check with the latest code and let me know if it's still causing issues. - David

Beryl plugin do not do multiple levels of blur and all is faster when having multiple translucent windows. Another thing is blur effect in fade plugin. It make fade slow and ugly. Cedric
