Draw to FBO with particular viewport

[Reon90]

Draw to FBO with gl.viewport(1050, 0, 1050, 1400).
It gives me wrong result in FBO and correct result in canvas

Also it shows correct texture when I pass it by uniform

In the uniform you see the full texture and in the Frame Buffer: 0 capture you see only the part corresponding to the set viewport ?

I guess I am missing something ?

@sebavan in the Frame Buffer: 0 capture I see full texture but without viewport offset. In this example, there should be 1050px offset from left side, but there is no.

Also I see that offset was applied

Could you share a link to the repro ? that would be much helpful.
