Hi,

That's expected. The bug fix clamps the buffer size in the surface state. It
doesn't modify glBufferData's behavior.

I'm not sure what you'd assert in the max-size test. A new test can be created
or an existing one modified. I'm guessing adding a test for
GL_ARB_shader_image_size would be the easiest way to test the issue.
