Is there a way to make Ocemp displays transparent? I tried specifying the color attribute with an RGBA value like (255,0,0,0,128) and got an opaque background.
I am speculating that the working surfaces Ocemp GUI creates do not have an alpha channel, and so cannot use the alpha value in the RGBA.
My workaround was to assign to the private _screen attribute directly, rather than the screen property for the renderer, and thus bypass the background creation method altogether,
but it would be good to have at least the background surface created as RGBA so that alpha values in the color attribute would be meaningful.
