Flashing background during generation

[asbrwl]

When the application is working on generating an image, the output area flashes colours.
This can be disturbing, and in extreme cases also cause seizures especially for people with a history of epilepsy.

Would request considering disabling this action, especially since the spinner already performs the function of showing that work is happening in the background.

I second this. The pulsing grey background makes me feel nauseous, please do disable this during generation. Honestly it's very off-putting. Thankyou!
