Hii @mwestphal I was able to fix the issue with scalar bar rendering above imgui console thanks to help from @Meakk.
This pr has those changes: #1951.
I was not able to solve the issue with axis rendering above imgui console, and I do not have any idea how to solve it, so maybe you can fix that.

Well, the scalar bar is the one that is causing issue so its great already!
