MOI viewport lag

Hello,

I've been experiencing lag with extrude and offset operations. Is the following normal?

The video shows, when extruding, the interactive preview of extrusion stops after awhile and it will only refresh when I lift my stylus up from my tablet or leave my mouse standing still.
After that it remains interactive for awhile and the stylus/mouse needs to be still for it to refresh.
