So i have this roundedPanel Component working very good. The corners are smooth as they should be, but that lasts till i set an image as background:

For more context basically what i want to do is have my winform app which the form is color whitesmoke and the transparencykey is whitesmoke and i have 2 panels on it open, and its topmost so its overlaying over everything, and if im focused on another app like my browser and i press a key it hides the panels, but if i press the key again it shows it again even if im not focused on the form.
