Hi,
I don’t know about you, but I have to see if Preview Sclaling is active every time.
Or maybe I haven’t found the option yet…, then, please, give me an advice.
TIA 
Best regards
If the change in video quality isn’t clear enough for you, you can just go to Settings>Preview Scaling to see what it’s set to. Or you can just quickly hit one of the shortcut keys to make sure it’s set to something. 
Or you have e.g. a symbol near the Source Player…
Is that simple enough, even for small mind like me…?
