System Information
Operating system: Windows 10 64-bit
Graphics card: Not applicable

Blender Version
Broken: 2.80 64-bit installer 9/2/2019
Worked: Cylinder displays correctly in version 2.79b

Short description of error
Upon further investigation problem seems to be confined to Object mode only. Cylinder seems to display normally in Edit mode, front orthographic.

Update (9/27): If I add a curved path and go to Object mode to scale it to length it disappears from view in both Orthographic and Perspective views. It appears in Edit mode but the scaling works differently in Edit mode for some reason. In Object mode one end of path remains anchored when scaling on Y axis, for example, but in Edit mode scaling occurs in the positive and negative directions simultaneously.? Not a show stopper but puzzling.
Again, the translation and scaling icons are still visible but not the object. Other objects remain visible selected or not. Perhaps it has something to do with the selection order; just a thought.

This may not be the correct place for a suggestion about Blender version information but it could be helpful, particularly for bug reports and such to put version information in the main menu under 'About' as in other Windows apps.

Original Complaint
Create cylinder mesh, 64 facets, no end faces, rotate 90d around X axis, scaled on X,Y,Z by 3 to 4. If you switch to orthographic view and try to view the cylinder end on its outline is not visible. You can see the object pivot or center of mass and any manipulation icons but not the object itself. Zooming has no effect. I could discern a couple of pixels sometimes when zooming to try to find the object but it is unknown whether they were part of the cylinder although they did display in the typical orange selection color.

Exact steps for others to reproduce the error
Simply create as described above and the results should be the same. No apparent issues result when same cylinder is created in version 2.79b.

The new outline is done in screenspace, If the selected object does not cover any pixel, it cannot produce outlines. This is a known issue since 2.80 and an implementation limitation.
