Of course, your graphics driver has probably changed over the course of
those 5 years, so maybe the driver bug simply wasn't present earlier.
Could you please open a bug-report to the maintainers of your graphics
driver and try to make sure it's fixed there?

Of course it's possible.
But it seems unlikely, since AFAIK the acceleration code only affects
what/how the pixels are written but not how the X server talks to
the application.
