Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages Enabling the Blur plugin seems to break the Zoom plugin. If both are enabled and I hit Ctrl+= to zoom in, the screen freezes. (The mouse moves, but everything else is like a static picture.) Hitting Ctrl+- or Ctrl+0 to return to 100% zoom brings the screen back to normal. If I don't enable the Blur plugin, the Zoom plugin works properly. (On intuition, I just tested the Magnifier plugin and it has the same issue. When the Blur plugin is enabled, the Magnifier won't magnify.) Using Kubuntu 4.2.00 packages, nvidia-glx-180 (180.11-0ubuntu1~intrepid1) driver, xorg (1:7.4~5ubuntu3)

Created attachment 33802 [details] Backtrace of KWin Zoom + Blur Crash
Comment on attachment 33802 [details] Backtrace of KWin Zoom + Blur Crash I successfully managed to crash KWin on KDE Trunk after enabling both the Zoom and Blur plugins ... and here is the backtrace; I can confirm this bug exists in both KDE 4.2.3 and Trunk.
@Dylon: your crash is completely unrelated to the problem described in this bug report. As you can clearly see the problem of the reporter is a black screen and *not* a crash. That's a big difference. Please open a new bug report for the crash. And btw. the crash happens in a code path which does not exist in 4.2.
Just to make it clear, in case it matters: The problem does not result in a black screen, but in a 1-step zoomed screen. However the screen does not zoom further in, nor does it pan when the mouse is moved around.
As there will be a new blur effect in KDE SC 4.5 it does not make sense to keep this report open. If the new blur effect should show the same issue, it is a new bug unrelated to this one.
