In this test, we create canvases use nondefault graphicsConfigurations and display them on the multiscreen enviroment. There are stripes showing up on the place where the text string suppose to displayed on. In my test, this only happens on the second monitor, there is no stripe appear in the first monitor, and the strings displayed well on the first monitor. But on another machine, we noticed that the text string does not show up at all on some canvases even without stripes. The problem is reproducible.
