Scrolling jitter

[Ralph DiMola]

No I did not set either of those. In fact they are all created dynamically
every time the card is opened. Now that you mention it I don't even set any
scrolling modes. Create master group, create sub groups , put in fields and
images in to sub groups and let er rip. Maybe my stuff is not complex enough
to be a problem?

Actually, did you adjust any of the default values like tilesize or
compositorCacheLimit? I wonder if that would help.
