Issue: When using RPR and switching the viewport to Material Preview or Render the viewport becomes a white overlay when viewport denoising is enabled for "Viewport Mode" Interactive. Its as if the gamma of the whole scene is doubled or tripled. When denoising is turned off the issue disappears and you have the expected result, similar to cycles although with all the fireflies and noise because Denoising is disabled and low samples. Using GPU Rendering.

To reproduce just open file and enter material preview mode or render mode in the viewport with denoising enabled for Interactive Viewport Mode. Then turn off denoising to see expected result.

hi, in the interactive mode now the denoiser is working correctly with FSR only, without FSR - you see that's the results
