    Description

      There is a project of mine developed using qt5.1, which using QListView as the main view of the program, loads about 800~2000 rows datas. When I was using os x 10.8 system, it works fine, but now, when I upgrade my os to newest 10.9, I recompiled the project, it becomes very slow when display the listview after rows inserted, and cpu usage of the program come to 100% nearly.
      I think this bug is produced by the change of api of new osx 10.9.
