Why does the view not update when zooming or panning the map view?
A loaded basemap layer overloads the graphics card.
1. ArcMap menu Customize > ArcMap Options > Data View tab > Uncheck "Enable hardware acceleration for supported layers".
2. do not load a basemap layer in the TOC.
3. ungroup the loaded basemap layer.
4. install the latest driver of the graphics card.
Note: It also affects the capture of lines, which become visible only after moving them.
