GL_RGBA should corresponds to ABGR8888.
Try GL_BGRA, which is ARGB8888.
Note: Actually it is possible intel vs gallium drivers GL_RGBA and
GL_BGRA have different argb ordering. So perhaps try both so that all
drivers are happy.

I am attempting to pass a GL_TEXTURE_2D directly to a Wayland
compositor by first converting it so an EGLImageKHR and then to a
wl_buffer.
eglCreateImageKHR appears to work fine but when calling
glCreateWaylandBufferFromImageWL I get EGL_BAD_MATCH "unsupported
image format".
The GL_TEXTURE_2D is in GL_RGBA format.
Is this going to be possible or should I look for an alternative way?
I was originally blitting the texture to the default framebuffer and
then trying to use eglSwapBuffers. But for some reason eglSwapBuffers
was returning EGL_BAD_SURFACE even though eglMakeCurrent had no errors.
