Sorry to keep bothering...

mac opengl 3.3
My Issue/Question:

When I create a window with columns and flags:

ImGuiWindowFlags_NoCollapse | ImGuiWindowFlags_AlwaysAutoResize | ImGuiWindowFlags_NoSavedSettings

it animates to the width of my application. Then, as soon as I drag it to the right so the right border of the window hits the right border of my application, it animates to be what seems to be a minimum width. I can drag it left all I want and then move it around as long as the right edge doesn't touch and it won't shrink. After it shrinks, if I drag it back to the left, it will grow back to full width.

This worked with imgui code from a while ago. It would just make a window of a nice reasonable width and it would stay that way.

(you may want to mute, my trackpad clicks are kind of loud)

I removed code until I got to the point it was just calling my columns helper code:

void Gui::
columns(const char * column_region_id, std::vector<std::string> const & column_names, std::function<void(void)> column_builder)
{
    NO_OP_IF_NO_GRAPHICS;
    ImGui::Columns(static_cast<int>(column_names.size()), column_region_id);
    ImGui::Separator();
	for (auto column_name : column_names) {
        ImGui::TextUnformatted(column_name.c_str()); 
		ImGui::NextColumn();
	}
	ImGui::Separator();
	
	try {
        column_builder();
    } catch (...) {
        ImGui::Columns(1);
        ImGui::Separator();
        throw;
    }
    ImGui::Columns(1);
    ImGui::Separator();
}
