Imgui: SetWindowPos incorrect results in multi display

[seoyeon01]

Version/Branch of Dear ImGui:

Version: 1.69 WIP
Branch: docking

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_opengl2.cpp + imgui_impl_glfw.cpp
Compiler: Visual Studio 2017
Operating System: Win10

My Issue/Question:
Screenshots/Video

When moving the location using SetWindowPos on a dual monitor,
the result is unintended as shown in the picture below.

case1 ) window located on monitor1

case2 ) window located on monitor2

case3) window located on monitor2 + different size window

Standalone, minimal, complete and verifiable example:

// Please do not forget this!
ImGui::Begin("Example Bug");

if( ImGui::Button( "set pos ( 0, 0 )" ) )
    ImGui::SetWindowPos( ImVec2( 0, 0 ) );
ImGui::Text( "pos : %.f, %.f", ImGui::GetWindowPos().x, ImGui::GetWindowPos().y );
ImGui::Text( "size : %.f, %.f", ImGui::GetWindowSize().x, ImGui::GetWindowSize().y );

ImGui::End();

I searched for articles of FAQs, Readme, posted same issue etc... but couldn't find them
i'm sorry if i missed it

Thank you always.

It looks like the window is being clamping within the bound of the same monitor.

Please note that using SetWindowPos() is never recommended, you should use SetNextWindowPos(), but I agree there seem to be a bug in there anyway.

I pushed a fix to this bug now.
In your case the window coordinates were clamped within the previous monitor.
