Thank you for your report, but this is not a bug. If you need help learning or using Blender, please post a question on one of our community websites, for instance Blender's StackExchange, blenderartists.org or the #support channel on Blender chat.

Thanks for your replay.

I managed to frame the model on the viewport, but I still have difficulty centering the selected object and orbit around it. It makes {F9877900}modeling difficult.

Thanks for your replay.

Thanks for your quick replay. Does this also affect viewport performance? I have noticed that when my scene gets more complicated with several objects and textures, the machine slow down to a point that is impossible to keep working and I have to switch to Windows.

Thanks for the advice. re-adjusting the clipping made the trick. I thought it was going to be more like a video card related setting.

See Sample below

The issue is also happening on my PC

Working with the knife tool on version 2.81. It creates overlapping vertices and extra edges on top of the existing ones used to terminate the cut. Sometimes, the created vertices rest lose on the face and do not attach to the edge they were intended to be part of, therefore creating a messy typology and and a lot of extra work and time to fix. Excuse my lack of proper technical language to describe the issue, I hope anyone out there reading this post can understand what I am trying to explain. I could submit snapshots if needed.
