KMSDRM video regression
Describe the bug
Using v5.7.0 and KMSDRM (current RaspiOS (bookworm), Pi4/64bit), the video output is very slow and basically unusable. Booting the very simple AmigaTestKit results in a flickering mouse cursor and the start 'page' of the kit is shown in about 1 min.
Looking at the log, I see Amiberry is looping while re-creating the SDL2 window (newlines added by me):

To Reproduce
Compile Amiberry for Pi4, (PLATFORM=rpi4-64-sdl2) and make sure the installed SDL2 has KMSDRM video support, then start Amiberry outside a desktop env.
Expected behavior Video output to not be choppy/slow.
Desktop (please complete the following information):
- OS: RaspiOS 12 bookworm
- Version: 5.7.0
Additional context KMSDRM SDL2 video driver used, no desktop (X11/Wayland) involved. Maybe caused by 2428b3042581d6e24af75a67f353743d99a96f63 ?
Are you only seeing flickering in the GUI? In that case, that's normal. If you turn on the status line, what kind of FPS do you get?
The flickering is not in the GUI, I just start directly AmigaTestKit.adf.
If you turn on the status line, what kind of FPS do you get?
I'll try to add that to the .conf and re-test.
Here is the amiberry.conf file I have (saved with 5.6.6 I think).

Interestingly, if I toggle the GUI via F12, there is no slowdown. Also, if I toggle Show Line native and save the configuration for the AmigaTestKit.adf file, then subsequent starts don't show the slowdown and also the cursor mouse is gone/non flickering. Once I remove the .uae saved config and start it, the issue comes back.
