Raspberry Pi OS Bullseye now uses the Full KMS OpenGL driver by default, and not surprisingly, raspi2png doesn't work. I use this tool often to take screenshots with the mouse pointer and of OpenGL overlays. No other tool can do that.

Raspi2png is in the Pi-Apps app store and over one thousand people use it. As we continue to make the app store 100% compatible with Bullseye, we will be forced to remove your app if it cannot comply. Would you be willing to look into this again?

More of a workaround, but if you change the dtoverlay, then raspi2png will work again. Stumbled upon this trying to troubleshoot another old program on the new raspbian version. (So feel free to ignore this if it's not helpful)

/boot/config.txt Replace : dtoverlay=vc4-kms-v3d With : dtoverlay=vc4-fkms-v3d
