Menu-Screen Problem since amiberry v5.7.2

[Retro1968]

System: Raspberry Pi 4B. Problem exists with amiberry on RaspiOS 64 Bit and RetroPie.

Hello Dimitris, first of all, i thank you for your consistently reliable work for the excellent amiberry project! 👍

I have the following problem since amiberry v5.7.2. I am currently using amiberry v5.7.3.

I use a 4:3 monitor. In amiberry I set a resolution of 800x600.

Since amiberry v5.7.2. I have the problem as soon as I go into the Amiberry menu using the F12 key that the screen keeps "wobbling" there, as if there were difficulties fitting the screen into the 800x600 resolution. I have also experienced under retropie that sometimes F12 led to amiberry crashing immediately. But when you are in the menu with F12, the screen keeps wobbling.

I am attaching my configuration file. Please test with a 4:3 monitor in 800x600. conf.zip
