            Bug ID: 89152
           Summary: glBlitFramebuffer always "bad src/dst multisample
                    pixel formats", when src fbo is multisample
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

  --> https://bugs.freedesktop.org/attachment.cgi?id=113504&action=edit
simple sdl2 example

If I try to blit from a multisample fbo I always get:

GL_INVALID_OPERATION

or with KHR_debug callback:

GL_INVALID_OPERATION in glBlitFramebufferEXT(bad src/dst multisample pixel
formats)

This even happens when the target fbo has the same sample count.

--- Comment #1 from Michel Dänzer <michel@daenzer.net> ---
I'm hitting several other GL error conditions first:

Mesa: User error: GL_INVALID_VALUE in glSampleMaski(index)
Mesa: User error: GL_INVALID_ENUM in glFramebufferTextureLayer(target=0x1)
Mesa: User error: GL_INVALID_ENUM in glDrawElementsInstanced(mode=8ca8)
Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture
Mesa: User error: GL_INVALID_ENUM in glBindRenderbufferEXT(target)
glGetError = GL_INVALID_VALUE

Try running the app with a debugging build of Mesa in gdb and setting a
breakpoint on _mesa_error.
