You are probably mishandling the clipping rectangles in your render function.
Rectangles provided by ImGui are defined as
Each draw command needs the triangle rendered using the clipping rectangle provided in the ImDrawCmd structure (`ImDrawCmd->CllipRect`).
Rectangles provided by Dear ImGui are defined as
`(x1=left,y1=top,x2=right,y2=bottom)`
and **NOT** as
`(x1,y1,width,height)`
Refer to rendering back-ends in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder for references of how to handle the `ClipRect` field.
