Remove 1 Frame Delay On Text Drawn

This wasn't apparent in the preview build given to us by @gitrinitas at the start of the PyCore development process, but somehow found it's way into the build that we based it off of. No one has any clue how this happened to "reappear".

Current fix is to disable immediately present XFB, however this causes #117 as a result. Closing this issue should require a solution which also closes #117.
