Can not create valid EGLImage from render buffer

Hello,

I am trying to save screenshot of a qml quick controls application on nvidia platform(running QT on wayland) by using native opengl functions by using a render buffer with eglCreateImageKHR function and then send the EGLImage to another device through Qt socket communication. I can successfully create EGLImage that means there is no error from eglGetError function.I tried to check EGLImage by saving it to a bin file(also as png) but when I try to check the saved bin and png I see only noise on the screen as in the attachment.

Could you please check the issue with example attachment ?

Regards
