They can do that if there is support for multiple planes, or if it's possible to set a background color. Something has to be visible through that transparent pixel.

Yes there are two parts to kmsro, the display and the gpu/render side. I was a bit suprised that amd and intel are not supported. kmsro driver: [src/gallium/winsys/kmsro/drm/kmsro_drm_winsys.c](https://elixir.bootlin.com/mesa/latest/source/src/gallium/winsys/kmsro/drm/kmsro_drm_winsys.c) I just...

Thanks for the heads up, closing this.

I would accept patches to add support for that as long as it doesn't add lots of code to handle this very niche use case. Unfortunately [usb_sg_init()](https://elixir.bootlin.com/linux/latest/C/ident/usb_sg_init) does not support...

> very niche use case Rethinking this, it could simplify implementing the protocol where the pixel transfer isn't big like in tiny displays and e-ink/monochrome displays.

This is a very low priority project for me so I don't know if there will be any more releases, but if it happens I've put your request in my...
