Problems with GradientLinearBrush

Hi all,

I'm having a bit of problem with System.Drawing.Drawing2D.LinearGradientBrush. First I initialize a Rectangle object and then pass into the constructor of the brush together with the selected start and end colors. Next I use the same rectangle object to be filled by System.Drawing.Graphics.FillRectangle function. However, I get the following image.

Notice the extra line at the top? The line will be gone if you change the height of the rectangle to certain values. I just couldn't figure this out.

Please help. :cry:

Does anyone know? Please. :(
