Display problems in OpenGL viewports when using selection tools

Issue

You are trying to work with component selection or edit tools in an OpenGL viewport, but you get graphical display errors like the following: 

  • When you select polygons using raycast selection, the viewport goes white and the object turns blue, purple, or black. Sometimes the wireframe disappears.
  • When you select polygons using raycast selection, random polygons are selected.
  • When you try to select edges, no edges are selected.

Typical example of the display problems caused
by the anti-aliasing setting of the graphic card

Solution

Check  the Anti-Aliasing setting for your display driver. It should be set to Application Controlled.

If that does not help, or if you do not have an Anti-Aliasing setting, try installing the latest version of the display driver.
