I'm also getting some weirdness with the central white dot (and near the red axis) when the gizmo isn't visible:

This shouldn't return true if the gizmo isn't drawn.

if (isGuiGizmoVisible)
{
       ImGuizmo::Manipulate(...);
}

Here isGuiGizmoVisible is a boolean that I'm toggling on and off.

Maybe it's a different bug? Eh... I'm mentioning it here as a comment because they seem related.

That's interesting. Let me check that :)

@AndreiDespinoiu Do you have a call to viewManipulate ?

@CedricGuillemet No. Just the gizmo (ImGuizmo::Manipulate).

@AndreiDespinoiu Can you please try to replicate the issue in the sample? You'll need to comment the line to viewManipulate because this call interfers with view/projection matrix (I'll fix that soon)

Yes, it happens in the sample as well.

Add this line:

std::cout << "Result is: " << std::boolalpha << ImGuizmo::IsOver() << '\n';

before creating the sequencer, so that means at line 565 from main() here: https://github.com/CedricGuillemet/ImGuizmo/blob/master/example/main.cpp#L565

Obviously, you need this header at the top:

#include <iostream>

It doesn't matter if you comment out the ImGuizmo::ViewManipulate line or not.

I'm trying again to repro ... and I get the same as you. I'm investigating now :)

I just pushed to main branch and it should be fixed. Let me know if it works for you...or not !

All right! This is awesome. It's fixed. Thank you so much!

Now about the white dot in the middle that I showed in the second gif... I submitted it as a separate issue, which I hope you'll take a look at: #133. Thank you!
