我是Kivy的新手，并且一直在使用Richard Jones的FlappyBird模型作为开始。我目前正在使用Kivy 1.9.2-dev0（）并且喜欢使用python 2.7。我注意到，当我启动应用程序时，显示的图形大小只有一半。但是，窗口尺寸显示为正确的尺寸（288,384），但是如果我在窗口内跟踪我的位置，它将显示为尺寸的两倍。另外，我注意到x，y（0,0）位置在左下方而不是左上方？
这是我的代码：

这是我点击窗口右上角并显示其位置的屏幕截图。 Y轴似乎是倒置的，窗口尺寸现在也增加了一倍？
我也遇到了kivy 1.9.2没有为我的标签阅读Kv语言的问题，这就是我在main.py文件中添加了所有args的原因
任何帮助将不胜感激，
谢谢！
