I agree and in general when you change theme and revert to the installation default, I have issues too. I am forced to reformat and redeploy the Bittboy v3.5 image on the SD card to get access to the themes and default settings.

In order to make a backup of the theme and UI settings so revert more easily, any idea where these files are stored? I searched the main FAT32 partition as well as the EXT3 partition image (via 7z for Windows) and could not find such a trace, any idea? Thanks

The issue author describes may be a result of "Burn-in on TFT panels" and can be seen even on our phones.

Displaying a single e.g. bright image can cause the crystals of the pixels to retain a memory of the image in form of burn making a ghost effect on darker background (turning off/on LCD usually helps).
