Version: (using KDE 4.1.1) OS: Linux Installed from: Ubuntu Packages Open the Configue Window Behaviour menu. Tick the option enable desktop effect and go to the tab desktop effects enabled. Then leave the menu with the cancel button. If you open it back, you will see that the option is still ticked whereas the effect is not enabled.. The problem doesn't occur if instead of going to the all effects tab you switch to another menu on the left column and leave. The same control has to be done for the previous run I described.. Cheers everyone
is this still an issue in a later release of KDE?
@Martin: yes, the bug is still valid, just reproduced using KDE 4.6.1
more interesting would be in fact to know if it is still reproducable in master as the dialog changed.
The particular issue is gone, since the option doesn't work this way anymore. The general bug behind this is that the config is synced and reloaded on tab changes w/o emitting an "apply" / changed() signal. In other words: switching tabs implicitly saves the config (to disk) - to gain sync between the switcher setting and the "all effects" tab (and also the restrictions of the XRender backend) This is somehow a design bug :-(
