unity3d 中rect[2] <= rt->GetGLWidth() && rect[3] <= rt->GetGLHeight()错误的原因及解决方法

官方是这么解释的
http://issuetracker.unity3d.com/issues/camera-with-depth-only-or-dont-clear-throws-error-when-image-effects-are-applied?page=2#comments

Camera with image effects throws error when certain game view aspect ratios are used

To reproduce:

1. Create a camera with Clear Flags set to "Depth Only" or "Don't Clear"

2. Attach an image effect to the camera

3. Set the game window scale to 16:9

4. Enter game mode. Try resizing the game window

5. "rect[2] == rt->GetGLWidth() && rect[3] == rt->GetGLHeight()" appears in the console

Does not occur with version 4.2.2f1

Seems to be related mostly to the aspect ration of the game view and the image effects.

does not occur if game view is undocked

大概是说

1。创建一个相机设置为"Depth Only"或"Don't Clear"

2。附加摄像机的图像效果

3。游戏窗口范围设置为16:9

4。进入游戏模式。调整游戏窗口

。。。

解决方法：

在game面板中分辨率调成free，也许会好。。- -

这个错误只在unity中发生，不会在打包出的游戏中发生
