Jerky viewport navigation not fixed yet

Hi.
This issue is not fixed yet.
As you can see, from the attached video, there is an huge difference in graphics performance between Rhino 7 and Rhino 8 WIP.

I don’t know what you have changed in the opengl code but Rhinoceros 7 performs a lot better, super smooth and super fluid on my system.
I don’t know if it’s an AMD driver graphic issue. I use an AMD Radeon Pro 580X with the latest driver. I don’t want to force to install modified bootcamp not official drivers.
All my 3d graphic applications work smooth without any graphic issue.

Also, when working with Rhinoceros 8 WIP, after some minutes, all inputs through the keyboard become sluggish. If I write a text to create a layer or if I want to modify text, Rhino responds very slowly. I have already posted in this forum a video regarding this issue.

This is the systeminfo with the latest update.
