Can't round window corners

[Kon-Kam]

Version/Branch of Dear ImGui:

Branch: docking

Back-ends:

imgui_impl_win32.cpp + imgui_impl_dx11.cpp

Compiler, OS:

Windows 11

Full config/build information:

No response

Details:

The main window's corners are rounded, like Win11 style, but the independent windows' (I'm using docking) corners are completely square.

I've checked out all rounding variables both from the Demo window and the style variable from in-code, but nothing seems to work, not even the Window Rounding. I wouldn't think being able to round corners wasn't supported; that's why I'm opening this

Also my text is very blurry, which I don't know if it's a feature...

Window rounding is not currently supported when multi-viewports are enabled. Enabling it is non-trivial.

See #2766 and the various issues linking to it. (And subscribe to #7912 if you want updates.)

This looks like a DPI issue. Your app is not marked as DPI aware so Windows is scaling it up automatically, which makes the whole app blurry.

You can either mark your application as DPI-aware in your application manifest or call ImGui_ImplWin32_EnableDpiAwareness at runtime before you create any windows or window classes.

However proper frictionless high DPI support in Dear ImGui is still a work in progress so it won't be perfect with that alone. (In particular everything will appear very small by default.) You can explore the various issues tagged with the dpi label for current workarounds people are using.

Oh ok, thanks. And yes I'm aware of DPI, but didn't know how to use it correctly or what it was, so... gonna check that. Also I'm not closing this, because it may evolve into a bigger discussion.

Closing as the question was well answered by David. Please don’t ask two unrelated questions in the same topic, it makes things harder to find and label.
