Sorry, I don’t know what I’ve talked about. It was a wild guess. I know with X11 there is an option to have the backing store at X-Server-side to reduce the network traffic. But I don’t know if and how it is used by Qt and if there are pitfalls or bugs on Mac with it. > Can you still compile with qt4? If yes, is the bug present there too? Yes, I’ve built it with Qt4 now and no, the bug isn’t present there. Stephan
