My guess is that the reason this is happenin is because if it has to stretch the image its constantly remapping it then resizing it. If its a static size then theres none of that.

To flight flashing, you need to use double buffering. For a form, please use System.Windows.Forms.From.DoubleBuffered property, http://msdn.microsoft.com/en-us/library/system.windows.forms.control.doublebuffered.aspx[^].

It can practically eliminate flashing.

If you have flashing with some other control, you need to sub-class such control in order to get access to a protected method System.Windows.Forms.Control.SetStyle. You would need to add the styles ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint.

Please see:
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.setstyle.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.forms.controlstyles.aspx[^].

You can use this method with the Form as well as it is Control.

If you code is slow, you must be doing something wrong (double buffering can only made it a little bit slower), but it's hard to say anything without some code sample to manifest this problem.
