How to get the dimension of the render target in a ViewNode?

Hello, I am trying to solve a crash, and I found the easiest solution is to disable upscaling when the window is minimized. But I am not familiar with Bevy's rendering, and cannot figure out how to obtain dimension of render target.
I think the ViewTarget should be what I need, but its main_texture cannot reflect render target (which immediately becomes 1x1 once the window is minimized) in time. Its out_texture might be useful, but it is a TextureView which does not directly reflects a texture.
So, is there a way to get the dimension of render target in a ViewNode? Thanks.

Sorry, I found the real reason of this issue. I will close this topic.
