Xrender related question

[Alexei Babich]

Hello, all.

Having executed a piece of code listed below, I get a green window (as a result of calling XCreateSimpleWindow()) and a black rectangle on top of it (XRenderFillRectangle()). I still get just black, whatever color I set in the 'col' structure.
XRenderFindVisualFormat() points to the data field shown on the screenshot attached to this letter. 
Why doesn't the color of the rectangle depend on the 'col' parameters?

Thank you.

----
XRenderColor col;

//create simple window (near green background color) at x,y = (20,30) and width,height = (300,200)
abc = XCreateSimpleWindow(display, DefaultRootWindow(display), 20,30, 300,200,0,0,30000);
XMapWindow(display, abc);

//create default picture         
pict = XRenderCreatePicture(display, abc, XRenderFindVisualFormat(display, visual), 0, NULL);

//some color
col.red = 0;
col.green = 127;
col.blue = 250;
col.alpha = 250;

//fill rectangle at x,y=(20,30) and width,height=(40,50) with selected color
XRenderFillRectangle(display, PictOpSrc, pict, &col, 20,30,40,50);
