I'm guessing this is a Windows problem in which the GL context is 
destroyed when the window resizes; I've only tested under Linux.  If 
someone does need a resizable window, they should reload fonts after 
resizing on Windows.

You're setting glOrtho for a window size of 400x300, but the window size 
is 640x480.  On my computer this simply made it blurry, but I imagine 
it's also causing your artifacts too.  Change resoltion=(300,400) to 
resolution=SCREEN_SIZE to fix.
