i have activated the Transparent mode of GLFW.
i have a fbo blitted in the background of the app, imgui is on top.
i would like to define the alpha of the window corresponding to the alpha of the fbo.
he work like a charm, but when i set the alpha value to 1.
Imgui completly ignore that.
when i said imgui, i speak about the renderer on GLFW ( provided in example driectory)
I thinck its due to the blending but i dont know how i can correct that :
Here with alpha < 1 (the renderer is ok with that)
when alpha is 1 on my fbo, the renderer is affected a little bit, but we continue to see visual studio behind the app, also see the color widget (alpha is 100 but we see transparent background) :
