Tool turns invisible after click QuickSave

Hi,
I have a clean Zbrush 2022 installed. I had a issue that the tool turns invisible after click QuickSave. This issue is very easy to reproduce:

  1. Hide the LightBox.
  2. Select the Sphere3D in Tool.
  3. Click Make PolyMesh3D.
  4. Click and drag on the canvas to draw the tool.
  5. Click Edit mode.
  6. Click the QuickSave button.
  7. Move your mouse a little bit.
  8. The tool on the canvas will disappear. However you can rotate the tool to make it appear again.
