FYI this broke lots of games under wine 1.5.20, with errors like:
err:d3d:check_fbo_compat >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from
Post-pixelshader blending check @ utils.c / 1133
err:d3d:check_fbo_compat >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from
Post-pixelshader blending check @ utils.c / 1133
err:d3d:check_fbo_compat >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from
Post-pixelshader blending check @ utils.c / 1133
The failing line (in wine) is:
gl_info->gl_ops.gl.p_glCopyTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8,
0, 0, 16, 16, 0);
gl_info->gl_ops.gl.p_glGetTexImage(GL_TEXTURE_2D, 0, GL_BGRA,
GL_UNSIGNED_INT_8_8_8_8_REV, readback);
checkGLcall("Post-pixelshader blending check");
Apparently its trying to copy from a sRGB internal format:
9623 glTexImage2D(target = GL_TEXTURE_2D, level = 0, internalformat =
GL_SRGB8_ALPHA8, width = 16, height = 16, border = 0, format = GL_BGRA, type =
GL_UNSIGNED_INT_8_8_8_8_REV, pixels = NULL)
They seem to have fixed this in wine 1.5.23 (released Feb 1 2013) by removing
the CopyTexImage2D, but probably all wine version between
1.3.32 and 1.5.22 are broken.
Perhaps in the next release notes for Mesa (that would include this commit)
something should be said about having to upgrade wine?
Although this seems to be a new requirement in OpenGL core 4.3: OpenGL spec 4.2
and the "manpages" for glCopyTexImage2D
don't say anything about INVALID_OPERATION and sRGB:
https://www.opengl.org/sdk/docs/man/xhtml/glCopyTexImage2D.xml
Should the check done by your patch be restricted to OpenGL 4.3 contexts?
