The clipping/overlay is a known issue. I reported it awhile back here:
viewtopic.php?f=34&t=39012&p=257708#p257664The description showing up in the upper left sounds like you've got the GridScreenDescriptionOffsetSD/HD set incorrectly. It should be a quoted string in the format "(x, y)".
EDIT: Or, I guess it can happen if the screen is configured out of order as RokuChris mentioned.
