AFAICT it looks like this is from _glamor_egl_create_image() failing in
glamor_egl_create_textured_pixmap(). Alexandr, can you add debugging
output in the former to see if it's due to depth not being 24 or 32, or
due to the EGL create image call failing? And if it's the latter, it
would be great if you could continue the same approach down the call
chain to find where the failure originates.
