ID 596050 - The Viewer and NetworkMaterialContext display graphical artifacts when using NVIDIA Graphics cards with certain drivers on Windows Operating Systems
Problem summary
The Viewer and NetworkMaterialContext display graphical artifacts when using NVIDIA Graphics cards with certain drivers on Windows Operating Systems. The Viewer behaviour has only been reproduced on the Katana 8.0 line, however the NetworkMaterial context issues can occur in all maintained Katana lines.
Customer reported version Katana 8.0v1
Customer reported platform Windows 10
Steps to reproduce
1) Launch Katana and create a PrimitiveCreate and NetworkMaterialCreate node in the Node Graph tab.
2) Set the View Flag on the PrimitiveCreate node and fully expand the scene within the Scene Explorer tab.
3) In the Viewer deselect the geometry and manipulate the Perspective Camera. *
4) Enter the NetworkMaterialCreate node and create a UsdPreviewSurface node and then attempt to connect the output to the Terminals panel.
5) Scale the Node Graphtab while in the NetworkMaterialCreate context. **
6) Create a NetworkMaterialCreate node and enter the NMC.
7) Press tab and put down any combination of shader nodes.
8) Attempt to connect the nodes and move them around. ***
Expected behaviour *Viewer - Clear from graphical artifacts. **NetworkMaterial - The created UsdPreviewSurface node displays fine and works as expected, and the Terminals panel moves with the scaling of the Node Graph tab.
***NetworkMaterialCreate - Katana does not crash, NMC functions as you would expect allowing you to move nodes and use the nodegraph freely.
Actual behaviour *Viewer - Areas become obscured by a graphical artifact based on where the geometry previously was. **NetworkMaterial - The created UsdPreviewSurface node can display broken edges and randomly drawn lines, and the Terminals panel does not move with the scaling of the Node Graph tab. ***NetworkMaterialCreate - Katana crashes within a few seconds to a minute while attempting to place or connect nodes in the NMC nodegraph.
Workaround Unknown.
