Thanks for letting me know that's the case, I've opened an issue in the picamera2 repo.With the current DRM/KMS support from picamera2 you can't.
DRM/KMS supports passing the same buffer to more than one plane, and assigning those planes to different CRTCs (displays), but it requires userspace to set that up. You then also get a few gotchas for situations like if the displays are running at different refresh rates.
It is a solvable problem, but would take some time (partly in creating a mechanism to configure it all). I'd suggest you create an issue on https://github.com/raspberrypi/picamera2/issues so that it doesn't get lost in the forums. Please include a link back to this forum thread.
Could you give me some pointer on how I would go about solving this?
Thanks!
I'm not using any window manager, just stock pi os that boots to cli, or even pi os lite.Which window manager are you running? Have you tested labwc already to see if that makes a difference?
