Display draws horizontal lines, when image is too wide?

When I load a file, that is wider/full width of the screen. It draws some horizontal lines (Looks like some kind of overflow error) Everything works fine, but the image is messed up and “not nice” to look at. I have homing top-right on the controller, screen origin top-right and same in LB. Controller is 6445G

Do I need upgrading FW on the controller ? And where to find ?
