--- Comment #6 from Martin Gräßlin <mgraess...@kde.org> --- > KDE notified me that compositing settings had been reset oh that's interesting. So probably this dialog: "Desktop effects were restarted due to a graphics reset" This means that the driver was not able to handle the situation properly and performed a "reset". That's probably very related to the problems you see and might indicate that they are rather in the X-Server and/or drivers. To verify: please have a look into /var/log/Xorg.0.log for anything which looks suspicious (e.g. warnings when changing screens). Also please provide the output of: * qdbus org.kde.KWin /KWin supportInformation * glxinfo -l -- You are receiving this mail because: You are watching all bug changes.
