After I loaded up the jpeg impage, the upper right coner glitching showed up. If I would draw a land coverage area around the glitching area, the glitching part impage would also turn to the land coverage i chose. Could this be the problem of surface underneath? or why the image would show up strangely?
I believe you're seeing the terrain surface clippigng through the imagery.
Click on the "Manage Surface Layers" button on the Home tab of the ribbon bar and make sure that Terrain Surfaces it turned off.
