See the attached screenshot. Pay special attention to the Personal Toolbar and the area in the lower right-hand corner of the border of the search button/URLbar area. There are two separate problems here: the corrupted images on the Personal Toolbar (which occasionally fix themselves upon a minimize and restore, but not consistently), and the small black dot on the edge of the groove of the area there. I didn't find any similar bugs in Bugzilla. EXPECTED RESULTS: The images aren't corrupted. ACTUAL RESULTS: They are, unfortunately.
