patch0.diff

Does the attached patch help? If it doesn't, could you confirm that the problem is somewhere along the A8+A8 path by running patch1.diff?

The patch1 works well, I have not tried Patch0. I try the Patch0?

Thank you.

Please do, patch1.diff just prevents A8+A8 from being accelerated.

With much improved path0.
I only noticed a flaw in a letter across the desk.
You can see in image_patch0. (font size giant to view)

With patch1 is perfect. You can see in image_patch1

This should be fixed in master now, so I'm closing the bug.
