screen size since last firmware update

Since I updated to the latest firmware my screensize keeps resetting itself. basically I have to set my screen to 92% in display to get the white lines and have all parts of screen showing. I then save this and use my minix, but every few days it I will notice that my clock is partially off screen and I have to go back and the display is at 100% again and I have to re-do the screen size. This has happened at least 10 times.

HAs anyone else had this problem and if so is there a resolution?

Any...
