Pull request overview
Adjusts lighttable thumbnail rendering so the “working…” overlay doesn’t remain visible when a smaller (fallback) mipmap is already being displayed during higher-resolution surface retries (e.g., full-preview 100% zoom transitions).
Changes:
- Updates busy-flag behavior to avoid showing the loading overlay when
DT_VIEW_SURFACE_SMALLERis returned but a usable surface already exists. - Adds explanatory comments describing the fallback-mipmap scenario and why retrying should continue without obscuring the image.

Fixes #21812
A full-preview 100% zoom can temporarily render a smaller mipmap while the requested level loads. The thumbnail kept its busy flag set during those retries, leaving a stale
working...overlay visible. Keep the retry timer, but only show the busy message when no usable surface is available.Testing:
