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.
There is no difference between Wayland and X11 in GPU the both uses it. make sure you have build it as hp your libraries or try to uses the latest yocto BSP.
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.
