Burn-in prevention suggestion
I'm contemplating to buy an LED monitor soon. But I'm worried that the GNOME Shell Activity bar will burn-in. Therefore I have the following suggestion to prevent burn-in.
In the Activity menu, the top Activity bar only becomes slightly transparent. If this would become just as transparent as it is when the desktop is shown without any full screen windows open [screen1.png] then the black Activity bar won't burn-in that easily. At the moment the top Activity bar is still almost fully black within the Activity menu [screen2.png]. The text and icons within the Activity bar already slightly change color. But if this contrast was also a bit stronger then this would be a win for LED monitor owners.
