Description Ruchir Brahmbhatt 2009-02-01 08:04:53 UTC 
Version:            (using KDE 4.2.0)
Installed from:    SuSE RPMs

When we configure desktop effects, it doesn't check for conflicting effects. For example, we can enable box switch, cover switch and flip switch. Same for desktop cube, round, cylinder. It should check for conflicting effects and should allow enabling only one effect at a time like in compiz-manager.

For window switching effects there is the dropdown list preventing this problem.

Cube/cylinder/sphere are not really conflicting effects. They just share the same shortcut, which will be fixed as soon as I merge my git branch to trunk.

Nevertheless we need a way to handle conflicting effects.

I was just about to report a similar issue. Specifically: I've noticed that if I enable both the Minimize Animation effect and the Magic Lamp effect, they are actually both applied, which makes for a screwed-up animation. To better see this, change the lamp animation configured duration to 1 second - now you can clearly see the window being minimized twice, first the regular minimize animation runs quickly (with a slight distortion caused by the beginning of the lamp effect, if you look carefully), then the window re-appears in full size again and proceeds to do the lamp effect.

These should definitely be mutually exclusive effects, and there are likely other such combinations that should be disallowed as well.

Our new configuration infrastructure in KWin 5 finally supports conflicting effects and one can only select one of a group.
