Image of a Game Maker game affected by this bug.

This bug affects a wide range of applications; all games made with Game Maker
(well over 20,000) appear to be affected.

When running an .exe binary created by Game Maker 5.3A, 6 or 7 in a window,
screen corruption fills all of part of the screen. It appears that the game
canvas is drawn offset from the drawing area origin, leaving whatever occupied
that area of VRAM to be drawn in the spaces that overlap the game window.

Test case: practically any of the 17,000 games on yoyogames.com, as long as
they are run in a window. Fullscreen games currently crash the OS as part of a
different bug, so I cannot test whether the bug continues to happen.

Attached is an example of a game affected by this bug. The game canvas is
obviously drawn partly above the window area, and the bottom part is flickering
corruption.

Running the game in a virtual desktop approximately the size of the game canvas
somewhat lessens the problem by centering the canvas within the window so only
some corruption is visible, but the bug is still in effect during this time.
