Hello, I searched the forum and the bug database for this and did not find anything about it. I have a problem with Konsole. I am using KDE and the binary nvidia driver. The composite effets are enabled and my system is up to date. Sometimes Konsole's window disappears partially. Then I have to minimize and maximize the window to renew it. I did not recognize this behaviour when KDE 4.2 was installed on my system. Does anybody have similar problems? It is not a big problem at all. But it is a little bit annoying. Thanks for your help! Bye, Lars Tennstedt
