How to reproduce:
1. Create a URP template project
2. Import the attached unitypackage file named "Code_1269325"
3. Add the FractalMaster script to the Main camera and assign Fractal CS to the "Fractal Shader" field. Reference the same camera in the "Cam" field
4. Switch to the Scene view

Expected result: The fractal is rendered to the render texture which is then rendered in the Camera preview window
Actual result: Render texture is rendered on the Opposite side of the Scene window. A black bar is rendered at the top of the Scene view covering most of the window controls
