I'll make a screenshot of the glitch and post it (ticket #99]. I think 
it only happens OO is in a borderless window.

Well, if you dont modify the w and do modify x you will move the 
rectangle (shift x coordinate to 0 but dont modify the width). My code 
snipet modifies w to compensate for the shift in x by drawing a smaller 
width rectangle. So actually im only snipping the part of left of the 
screen (left of x coordinate 0).
