Hi, Im trying to setup sdrberry with a raspberry dsi 7 inch display. When the app start the screen shows double.

Thanks,

I think you are using the original raspberry pi 7 inch display, which operates in 24 bit colour mode. Sdrberry is setup with 16 bit color depth. The simple solution is to switch to the legacy video driver and configure 16 bit colour depth. By changing config.txt. In the install directory there are two examples for 7 inch displays. The bullseye setting probably also works for bookworm.
Change the settings below in /boot/firmware/config.txt to disable the vc4-kms-v3d video driver.

#Enable DRM VC4 V3D driver
#dtoverlay=vc4-kms-v3d
max_framebuffers=2
display_lcd_rotate=2
framebuffer_depth=16

The more complicated solution would be to configure sdrberr to use 24 bit colour depth. In the file lv_conf.h there is a setting for this. How ever I did not test this.

To rotate the touch interface you can add config.txt

dtoverlay=rpi-ft5406,touchscreen-inverted-x=1
dtoverlay=rpi-ft5406,touchscreen-inverted-y=1

if necessary, or change the touch interface in sdrberry.cpp
Hope this helps
