Version: unspecified (using Devel) OS: Linux I did an upgrade today to 4.4.86 (KDE 4.4.86 (KDE 4.5 >= 20100616)) "release 3" and from this time on, kwin always tells me that the desktop effects are temporarily disabled because they were too slow. The same setup worked smoothly until yesterday. The compositing type is openGL This is on openSuse 11.2 on a Fujitsu Laptop with 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) some maybe useful lines from Xorg.0.log: (II) intel(0): [DRI2] Setup complete (**) intel(0): Framebuffer compression enabled (**) intel(0): Tiling enabled (**) intel(0): SwapBuffers wait enabled (==) intel(0): VideoRam: 262144 KB (II) intel(0): Attempting memory allocation with tiled buffers.

Reproducible: Always
Please try to disable direct rendering in the advanced compositing options. This is most likely caused by the bugfix for bug #240956.
Yes, that helped. Now it works again.
Created attachment 48442 [details] debugging output this contains output from inxi, glxinfo and Xorg logs
HI all, I have just upgraded to KDE SC 4.5 RC1 and I am facing the same problem. I have an Intel 4500M integrated graphics card and things like cover switch and the genie effect used to work in KDE SC 4.4 but now they cannot be started. I am running Arch 64bit and I installed from. I have tried disabling direct rendering but that doesn't help. I am attaching some console output with hardware, glx and Xorg logs.
Enabling "Disable functionality check" in Desktop Effect - System Settings, apparently do the trick. as suggested in this link [1]. CPU util is still high tho [1] http://forum.kde.org/viewtopic.php?f=111&t=88944
I think we have some workarounds to this problem with disabling functionality checks, blacklisting the drivers and disabling direct rendering. So to me this is a worksforme.
