My background is white and stays white.
I change the settings to urban or one of the others but i still have a white background.
I even uninstalled enscape..restarted my computer installed again..
Still same problem... i need the clouds back
Whenever things go sideways and do something unexpected I'd recommend going to Presets and reset all settings. It may not get you back to where you want to be, but it gives you a better starting point.
