The problem is surely caused by a video driver, and not by GSX and, in fact, it's a known error message that has been reported in all forums even months before the new GSX has been released.
You are mislead thinking the problem is caused by GSX ( because it disappears when uninstalling it ), but it's not.
The problem is caused by your driver and GSX is *affected* by it, because it use a relatively new function offered by the sim, which is called Render to Texture (RTT), to display numbers on jetways and the battery charger display. Since these are new functions and not so many (if any) other addons use them, you are seeing this problem caused by your driver only with GSX but, it would probably happened just the same with another addon that use the same feature.
Installing the new drivers using the CUSTOM installation option to select a CLEAN installation, should fix the problem.
As the last resort, you can try disabling RTT with the Addon Manager menu, and restart the sim. You'll lose numbers on jetways though so, it's best if you fix your drivers rather than removing that feature from GSX.
