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? > Just occurred to me that it might be possible for that to be a bug > within Emacs which is only triggered when acceleration is enabled. WDYT? 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. Stefan
