window border(color) visible, Draw in 'window background'.

[BrunoGysin]

I followed the code example provided in:
#466

ImGui::SetNextWindowPos(ImVec2(0,0));
ImGui::SetNextWindowSize(ImGui::GetIO().DisplaySize);
ImGui::Begin("foobar", NULL, ImVec2(0,0), 0.0f, ImGuiWindowFlags_NoTitleBar|ImGuiWindowFlags_NoResize|ImGuiWindowFlags_NoMove|ImGuiWindowFlags_NoScrollbar|ImGuiWindowFlags_NoScrollWithMouse);

I've used it since to create an 'invisible' window,
which is the size of the application, which makes it simulate drawing in the background of the application.

but was using an older version of ImGUI, and today I updated.
but the window in which it should be 'invisible' now has a border.

I'm using bg_alpha_override = 0.f
this was supposed to be working.

Surprisingly this has been coming a few times, I wonder if I should instate a ImGuiWindowFlags_NoBorder that would only affect the WindowBorderSize, but not affect FrameBorderSize or child windows..

I believe that this should be resolved with bg_alpha_override = 0.0f

the problem with this solution is that it affects other windows.

You could use SetNextWindowBgAlpha(0.0f) but right now it doesn't affect the border (I think it should and i'll change that now).

the problem with this solution is that it affects other windows.

I don't understand. No it doesn't.
