The example at the top of the page is outdated as well as the instructions for how to set it up. The repository shows that you've split a lot of stuff into seperate files. I also noticed in imgui-rendering-SFML there is a reference to ImImpl_fontTex which doesn't exist anywhere as far as I can tell. It'd be nice to see you include an example in the repository. :)

I've updated the repository and main post.
The usage has slightly changed, but everything works now.

Sorry for my absence and lack of response, thanks for your patience.

Note that you want scissoring and not stencil. Scissoring is a cheaper operation than stenciling which rely on a buffer.

- For some reason it's not supported in sf::RenderStates. It's a rather rarely used feature but it's also trivial to implement so perhaps it could be added to SFML.

- Otherwise you can do the scissoring in a shader (which is possibly what a graphics card driver would do for do when enabling scissoring anyway). Pass the float4 cliprect as a uniform to your shader and do a clipping in the pixel shader/

( - Or last resort you might be able to use sf::View::setViewport() as a workaround for the clipping, but I don't know how SFML behave in term of performance when changing the viewport. but adding it to the shader would be more sane. )
