Subject: intel: Make a renderbuffer wrapping a texture have the same _BaseFormat.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7cac88679bb600f35694e91859c4682c04c32f7a;p=mesa.git

intel: Make a renderbuffer wrapping a texture have the same _BaseFormat.

Otherwise, when you asked for the _BaseFormat of an rb wrapping a
GL_RGB texture, you got GL_RGBA because that's what we were storing
the texture data as.

NOTE: This is a candidate for the 8.0 branch.
