Version: (using Devel) Installed from: Compiled sources Compiler: gcc 4.3.1 OS: Linux If I disable all KWin plugins except for Cube and Blur, and then I activate the cube view, I can't see any windows. However, it works if I disable Blur. No options in "Advanced Options" makes a difference. nVidia Corporation GeForce 8800 GT with their Evil driver 169.12 Linux 2.6.24-1-686-bigmem 24 bit color
I can confirm this Bug, as well as the Desktop Grid is affected. Disable the Blur effect does solve the problem. Tested on: Linux 2.6.24.5-x86_64 Geforce 9600 GT (Driver is 177.80)
SVN commit 885931 by graesslin: Disable blur effect when there is an active fullscreen effect. This makes cube & co. work if blur is enabled. It's a hack and the real reason why the problem occurs should be searched for. (I totally forgot to commit this patch) BUG: 167928 M +4 -2 blur.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=885931
This workaround is doing great for desktop cube/grid, but the black screen still remains when I use the slide effect. Again, disabling blur solves the problem.
Slide does not define itself as a fullscreen effect. Which it is. So changing this will make the workaround work in slide as well.
