MSAA FBO blit artifacts

Hi there.

In lastest drivers i have some problem.

Main opengl context created without msaa enabled. Created fbo with msaa (2x, 4x ... etc) and all draws happen here.

Finally calls glBlitFramebuffer to default\context buffer. And after it appears some artifacts on place AA subpixels.

If i replace texture format GL_RGBA8 to GL_RGB8 or another ( GL_RGBA12, GL_RGBA16 ... etc ) artifacts dissappears. Another one is to enable msaa on ogl context.

minimal code to reproduce
