Just saw your edit and details (they don’t appear in the e-mail notifications) there’s NO scaling as you have noticed, objects are displayed with the same pixel size, this is why they look the same way. Due to Dear ImGui issue ocornut/imgui#5301, the font scaling on HiDPI setup (only on macOS) is not correct and results in blurry text. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use What you can do is to scale the vertex coordinates output by imgui. Skia. Note that I want the scaling I have implemented since it saves performance, I just want to turn off image scaling from ImGui side. Scale software rendered mouse cursor (when io. Instead they should Back-ends: imgui_impl_glfw. I've used DPI awareness with many other opengl applications successfully and that worked fine for properly scaling the Windows window itself, so unless I'm missing something Windows DPI API doesn't fix imgui.

Ps: DEBUG = false to turn off debugs println() But moreover, if I'm right, if you actually insert a call to ImGui::SetWindowFontScale() in the child window of a window that already set the current window scaling, it'll actually multiply the two scale values together! (So, the scaling will go exponentially instead of linearly, if you add this call, i. io. dll Syntax [Serializable] public struct Rect : IFormattable. Scaling the fonts is done separately and is up to you. using the same value -- anything other I'm making windows in ImGui and am trying to make some windows for a basic demo, and found the ImGui::SetNextWindowPos()&ImGui::SetNextWindowSize() functions and am using them. * check I'm using the following code as wrappers to ImGui::BeginTooltip() and ImGui::EndTooltip() to make sure that tooltips always remain on-screen and unobscured by the mouse cursor.
