Public bug reported: In KDE 4.7.3, blur effect works fine using Open GL 2. In KDE 4.7.4, with blur and Open GL 2 on, effects are too slow and automatically disabled.
Under KDE 4.8 GIT, the system is unusable and slow when Open GL 2 and Blur are on in kwin settings. However disabling Open GL 2 and reverting to open GL 1 works. However it is still slower than what Open GL2 offers in KDE 4.7.3 ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/908336 Title: Intel GMA 950 is unusable slow with blur effect on KDE 4.7.4 and higher when using Open GL 2.
