InputText not scaling with SetWindowFontScale

[vulcan-dev]

Version/Branch of Dear ImGui:
Version: 1.83
Branch: master

Back-end/Renderer/Compiler/OS
Back-ends: imgui_impl_dx11.cpp
Compiler: MSVC
Operating System: Windows

My Issue/Question:
I've got a scale slider and everything scales besides InputText, I expected it to scale as I think that's how it should work.

Screenshots/Video
Scale of 2:

I'm drawing it in a child window, hence the border. I expect InputText to fill that area.

Scale of 1:

Standalone, minimal, complete and verifiable example:

ImGui::Begin("Example Bug");
ImGui::SetWindowFontScale(2);
ImGui::InputText("##input", buf, 256); // height will be the same no matter the scale
ImGui::End();

@vulcan-dev It turns out that SetWindowFontScale seems to be a deprecated function in master. It looks like it's no longer possible to adjust scale per-window.

The author also gives a tutorial in the code stating what you should do instead to achieve a scalable UI:

[OBSOLETE] set font scale. Adjust IO.FontGlobalScale if you want to scale all windows. This is an old API! For correct scaling, prefer to reload font + rebuild ImFontAtlas + call style.ScaleAllSizes().

See

imgui/imgui.h

Line 372 in 7e03ae3

IMGUI_API void SetWindowFontScale(float scale); // [OBSOLETE] set font scale. Adjust IO.FontGlobalScale if you want to scale all windows. This is an old API! For correct scaling, prefer to reload font + rebuild ImFontAtlas + call style.ScaleAllSizes().

Perfect, I'll try that out later when I have time.
Thanks for the help

Closing this, as, in spite of SetWindowFontScale() not being recommended in the current version, I am sure this perfectly code and repro works. In fact, I just pasted the repro and confirmed it worked. Issue was probably somewhere else in user's code.
