Subject: st: create renderbuffer's pipe_surface in st_render_texture()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0a56a4968786bd93d9117af2a0a3bda13ea71c4d;p=mesa.git

st: create renderbuffer's pipe_surface in st_render_texture()

Previously we created the pipe_surface during framebuffer validation.
But if we did a glCopyTex[Sub]Image() before anything else we wouldn't yet
have the surface.  This fixes that.
