Bug 256166

Version:           unspecified
OS:                Linux

This is a bug that I found with -every- intel graphic card I tried, on both Fedora, Kubuntu and Archlinux.

In short, every time kwin starts, it thinks that it has started desktop effects, while infact it has not, and if you disable and enable them back, the effects come back working normally as they always did.

To explain better, I had to put the following script in .kde/Autostart, to make everything work:

#!/bin/bash
sleep 5
qdbus org.kde.kwin /KWin toggleCompositing
sleep 5
qdbus org.kde.kwin /KWin toggleCompositing

This effectively starts KDE with desktop effects.

Reproducible: Always

Steps to Reproduce:
Logout and login again.

Actual Results:  
KWin reports effects are on, but the panel is not transparent, ...

Expected Results:  
Compositing should be really on.
