I've tried resetting the NVRAM/PRAM and the SMC, but the previous window is still noticeable. I've activated the reduce transparency button, but the new window is still transparent and it looks like the old window was burned onto the screen. When I take a screenshot of the display, the problem doesn't show in the picture.

Hello _thetuna,
Thanks for asking the Apple Support Communities about image persistence.
It is normal to see a bit of image persistence on Retina Displays or even on the Apple Cinema and Thunderbolt displays. The reason for this is because of In-Plane Switching (IPS) technology. IPS technology enhances the viewing experience by providing full 178-degree viewing angles in all directions. So what that means is that the image should look flawless from all angles of the display with multiple people looking. This article talks about this: Avoiding image persistence on Apple displays - Apple Support
"When you leave an image such as a login window on an IPS display for a long period of time, you might temporarily see a faint remnant of the image even after a new image replaces it. This is called "persistence," "image retention," or "ghosting." It's normal behavior for an IPS display, and the faint image will disappear over time."
You can prevent image persistence by using the display sleep feature to turn off the display when it is not in use. You can also use a screen saver to make sure that a static image isn't on the display for long periods of time. Both of these features are on by default in Mac OS X, but you can adjust the settings as needed. I personally use Hot Corners to quickly activate a screen saver.
To prevent image persistence, enable the display sleep feature:
1. From the Apple () menu, choose System Preferences, and then click Energy Saver.
2. Click the Battery tab.
3. Set the "Display sleep" slider to a brief interval of time (such as 15 minutes).
4. Click the Power Adapter tab and make the same change.
If you see a persistent image on your screen, you can use the screen saver to eliminate it:
1. From the Apple () menu, choose System Preferences, and then click "Desktop & Screen Saver."
2. Click the Screen Saver tab and choose a screen saver.
3. Set the "Start screen saver" time to be shorter than the "Display sleep" and "Computer sleep" settings in the Energy Saver pane of System Preferences.
4. To clear the persistent image, allow the screen saver to run for approximately as long as the image was being displayed or you can activate the Hot Corner for the same amount of time.
Cheers.
