Resetting viewport of camera with orthographic projection results in stretching

[barsoosayque]

Bevy version

0.10.1

Relevant system information

`AdapterInfo { name: "NVIDIA GeForce GTX 1660", vendor: 4318, device: 8580, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "525.89.02", backend: Vulkan }`

What you did

In one system, I set camera.viewport to a custom Some(Viewport { .. }) with physical_position and physical_size (I got them from egui). After some time, in another system, I did camera.viewport = None.

What went wrong

Rendering becomes stretched, as if it would retain the same viewport size I set before resetting it, but stretching it to the whole window.

Additional information

I'm not quite sure what's wrong since I'm not very versed in rendering, but here are some key points I noticed while trying to debug this issue:

• The same code worked on bevy 0.9;
• I change viewport to None using a Query<&mut Camera, With<Camera3d>>::get_single_mut. If I add &mut OrthographicProjection as a second query param (and do literally nothing with it), it wouldn't stretch, but it would still render as if the viewport is the old one (the one I set to egui rect);
• Changing window size fixes the problem.
