Input Faces search refreshes endlessly after typing more than one character

[t3nka]

Summary

Filtering the Input Faces list by name reportedly causes the image list to refresh endlessly once more than one character is typed.

Reported Behavior

When typing into the Input Faces search field, the image list begins refreshing repeatedly after the search term is longer than one character.

Search reportedly works fine in Target Media and Embeddings.

Expected Behavior

Input Faces search should filter the image list once per input change and then settle, matching the behavior of Target Media and Embeddings search.

Reproduction Notes

Reported reproduction path:

1. Open Input Faces.
2. Start filtering by name.
3. Type more than one character.
4. Observe the image list refreshing endlessly.

Additional Context

• Source: summarized Discord reports
• Reported by: Miso
• Affected area appears specific to Input Faces search/list refresh logic.

Triage Notes

This may involve a search text change handler, model/list refresh signal loop, or state update that re-triggers filtering continuously.

I tested this again on current dev and could not reproduce the endless refresh behavior.

Looking through recent history, this was most likely fixed by 31100b1 (Avoid re-entrant filtering by deferring list updates), which removed the re-entrant QApplication.processEvents(...) call from the filter update path and now applies list visibility changes via a deferred QTimer.singleShot(0, ...) update with a sequence guard.

There was also later stabilization in PR #242 / bdbce05 (Batch fixes and Input faces loading fix), which added queued/batched UI updates for Input Face thumbnail loading. That should reduce flicker/refresh churn while input faces are still being added.

Closing as fixed / no longer reproducible on current dev. If this still happens on a fresh current build, please reopen with the exact build/commit and whether the search was performed while faces were still loading.
