Misbehaving GUI when i through libigl to use imgui

WhyNot134 commented 3 months ago

Version/Branch of Dear ImGui:

Version 1.90, Branch: master (master/docking/etc.)

Back-ends:

imgui_impl_glfw.cpp + imgui_impl_opengl3.cpp

Compiler, OS:

Windows10 + MSVC2019

Full config/build information:

No response

Details:

Menu is drawn fine in the libigl EXAMPLE 106 but problem comes when I interact with the window.

Before clicking anything, hovering over menu items highlights them as I would expect, but if I click on one of them (say, "Show texture", for example), A) nothing happens in the window, B) this is now the only GUI item that highlights when the mouse is hovered over it. I cannot interact with the mesh, rotating, scaling etc with the mouse or keyboard. The GUI is essentially now locked. Clicking on the same GUI item does nothing.
If, upon the window opening, I first interact with the mesh with a click (ie rotating, translating etc) with the mouse, this is now the only thing I can interact with. I cannot use the GUI menu to select checkboxes etc. The GUI elements do not highlight when I hover over them.
If, upon first opening, I use the hotkeys for stuff (such as "f" to toggle face-based rendering), the corresponding GUI checkbox changes. Once I click on anything however, the GUI locks again.

Using latest versions of libigl, imgui etc.

I have no idea what igl is nor what the code looks like.

Since you didn't post any code, I have to assume that the problem occurs with unmodified example sources from the libigl project. I'm not familiar with libigl, but it looks like this issue would be better located in that projects issue section.

It seems like I have the same issue as the details part described above. env: Ubuntu 22.04 + latest libigl + imgui 1.90.8. when I revert imgui version to 1.86, the issue disappears.
