Can the 2.2.1 renderer be plugged into 2.3?
I don't mind if it is slower
I don't mind if some graphical features are lost
I just want to try to eliminate one more variable. The 2.2.1 renderer worked on my ATI machines. If it still works now, then something that changed between 2.2.1 and 2.3 seems to be triggering a graphics driver bug.
