Hi Farshid, An interesting result. I'm afraid I can't recall the reason for the change, it will have been done quite a while ago. subversion's revisions might be able to unearth why sizeAdjustment is now 1- but it's pretty likely it was an attempt to improve one aspect of rendering so if we change it there is good chance that we'll improve on one area but make another area worse. If we can find out what cases require sizeAdjustment of 1 then perhaps we'll be able to build a test that reproduces both the issue you are seeing and this other one then we can come up with an all round solution.
