This should actually have gone with 4.9.1 Please provide the output of qdbus org.kde.kwin /KWin supportInformation also see bug #304375 and esp. bug #306079
Also ensure that you really have 4.9.1 of KWin - distros were asked to hold back the kde-workspace package
Sorry, my mistake, arch upgrade failed because I have compiled kwin from source. Now with upgrade I have kde 4.9.1 and the problem is resolved. Thank you for yours awesome work. Bye
