I have debugged this a bit more... The header is just rendered as background color - but not the transparent overlay giving the gradient gfx... ( altough the header background color isn't rendered after the scroll down / up anymore - and I think this behavior maybe ok while knockout is turned on...) But why isn't the gradient renderer? Because the image shall be drawn completely outside of the clipping rectangle ( clipping is from x: 0, y: 0, x1: window_width, y1: 40) - the plot function is called with 250 as y coord - that's not within the clipping rectangle... so the image will never be drawn. I haven't seen documentation for that case... Yes, I know I must fill the clipping region if the image has an repeat flag, but I won't fill the clipping if the image is outside of the clipping rectangle... And yes, I have knockout rendering turned on.... I hope somebody can help with this - don't just expect others to understand what should be done with the coords outside of the clipping rectangle passed to the plot_bitmap function... Greets, m
