Version: unspecified (using KDE 4.5.95)
When changing desktop effects settings, if an effect could not be enabled, there‘s a notification stating which effects could not be enabled.
It would be nice to have an indication (error symbol, or whatever) next to the effect itself in the effects list if it is checked but could not be enabled.
