Comment 4 for bug 770461

Ok, with some badly needed help from jabiertxo, I finally got it to refresh at runtime. Just click or unclick the option to have the render method for offsets change as soon as you do.

Please let me know if you find any problems, or if you object to adding this option for those of us who could benefit from not having artifacts (while we wait for a permanent fix) and the ability to switch from one render method to the other at runtime.
