Hi @rubenverhoef ,

This looks like this might not be compatible with the display method that cam_overlay uses, dispmanx overlay and gles

https://www.raspberrypi.org/forums/viewtopic.php?t=159853

The standard camera and video decode apps that drive the display from the gpu cannot be used when vc4-kms-v3d is enabled. Apps that use dispmanx for overlays or performance reasons (e.g. emulators) cannot be used.

If you're using X11, you could try compiling it in that mode? make clean && make DISPLAY=x11

Okay i will try and see what the performance and usability are.
