Support GPU between X11 and wayland on I.MX6

Hi all

    I want to know the different of using GPU (opengl) between X11 and wayland on I.MX6DL.

    Because I found my Qt widget project runs with high CPU on X11, I think it doesn't use GPU to process the interface,all the paint,update are process on CPU.

    So I want to know that Wayland is better than X11 or not about GPU.

Best regards

Mihan

Thanks @Bio_TICFSL 

   I'm building the image 4.14.98-2.0.0. for xwayland. How to know the backend it use when I compile my project?

   Can I only update the rootfs? I'm using 4.1.15-2.1.0 for X11. 

 Best regards
