1. fshack: Resolve fbo for glCopyTexSubImage2D …

   GL_INVALID_OPERATION is generated if: the effective value of GL_SAMPLE_BUFFERS
   for the read framebuffer is one.
   
   This API works by spec with a system multisampled renderbuffer BUT returns
   error with user-defined multisampled renderbuffers
   
   MESA project introduced a workaround for Penumbra game:
   https://gitlab.freedesktop.org/mesa/mesa/-/commit/8ced03437d62b38dc2d8c1bd43c005aedcaf7f72
   
   But it might break other games, so it need to be resolved in Proton layer
   
   Note: Pure WINE does not have this issue, it's only Proton wine fail
