Description
Whenever I switch between my monitors and run my program I get an instant crash before the first render. I narrowed it down to the UI drawing to a slightly bigger frame. I tried to recreate it in the example mentioned in the title and I also got the same error. A restart of my PC fixes it sometimes.
[2023-02-24T15:14:51Z ERROR wgpu::backend::direct] Handling wgpu errors as fatal by default
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In a RenderPass
note: encoder = `pixels_command_encoder`
In a set_scissor_rect command
Scissor Rect { x: 0, y: 0, w: 911, h: 650 } is not contained in the render target Extent3d { width: 910, height: 650, depth_or_array_layers: 1 }
I tried tweaking the code, but I couldn't find a solution. Any advice?

Research direction
Start with the imgui-winit example and trace how its render target dimensions reach the set_scissor_rect command. Reproduce the monitor-switching case and compare the requested 911x650 scissor rectangle with the 910x650 render target; done means the example no longer triggers the validation panic.
