[arch-general] Qt Creator black window on designer

Hi, I have QtCreator installed on my system. When I switch to designer mode (by opening *.ui.qml file) some of the window areas goes black, application start to response slowly and the crashes. This happens on both Nouveau & NVIDIA drives (If this matter). Does anyone knows to solve this problem?
