Short description of error
Reference images spontaneously vanish in the viewport when sculpting. The orange bounding area of the image is still selectable, but the image vanishes. Over time the viewport continues to degrade and other things like metaballs and entire meshes can suddenly stop rendering.
Exact steps for others to reproduce the error
-Drag an image into the modeling view of blender.
-Start making a base mesh from metaballs
-Convert to mesh and start sculpting.
