Graphics does not draw over the whole screen
I wrote a snake game using WinForms and Graphics object.
During the game, I draw somewhere on the form, but I've noticed that there is an area on the screen that the Graphics object can't draw there.
The form doesn't sprawl all over the screen, actually, it's size is 768x565.
So when I place it at the top-left corner of the screen it works perfectly, but at the center it's kind of cut.
Look at these:
When the form is placed at the top-left corner:
When the form is placed at the bottom-right corner:
You can see that now the snake is cut.
Please tell me if you know why it happen, thanks.
