Variable: preview-keep-stale-images

preview-keep-stale-images is a customizable variable defined in preview.el.

Value

nil

Documentation

Keep the last preview image visible even when the source changes.

If non-nil, a preview that was just edited retains its previous image while it sits in the disabled state instead of showing the construction icon. When nil, the icon appears until the refreshed image arrives.

The value of this variable is ignored when preview-visibility-style is off-point. In that case, stale images are never retained.

This variable was added, or its default value changed, in auctex version 14.2.0.
