Worked: Not sure if it ever worked in 2.8 but I noticed first time maybe 1-2 months ago
Short description of error
The viewport is slow and laggy when in Eevee or workbench, runs smooth when turning off overlays or switching to cycles.
It seems to be somewhat related to having an object selected (even if just a standard cube).
The smaller the 3D view is the smoother it runs.
Exact steps for others to reproduce the error
I open blender and rotate the view.
