Short description of error
While doing some regular testing in 2.83, I noticed that the current vertex painting system does not work nicely with Sculpt Mode. I thought the problem might have been related to Delay Viewport Updates because the bug only appeared when sculpting and undoing/redoing in relation to how zoomed in or out the viewport camera was to the model itself. However, toggling it on and off did nothing, so I am left puzzled.
Exact steps for others to reproduce the error
- Take a human sized sculpt of several tens of thousands of vertices and paint it in Vertex Paint Mode.
- Switch to Sculpt Mode.
- Make any change to your sculpt with the tools available while zoomed in on the model.
- Zoom out. The vertex painting artefacts should be fully visible now.
- Use undo/redo to activate or deactivate the bug. The bug will disappear when the entire model is visible in the viewport, but appear if you are zoomed in and then you zoom out again.
