Could you look into widening the SKU search box on the Sales Order Screen to match the width of the field that it populates. Currently, the search box cuts off the SKU details as it is smaller and holds less characters than the actual SKU box once populated.
Have you tried to adjust SKU column width in the grid. It can be quite wide. Please check this short video that has some hints on UI features that might be not obvious https://www.youtube.com/watch?v=ZRkeqcaILO4
