Glad the GPU acceleration is working well on your 7900 XTX!
As you say, the stuck/repeating lines are basically coming from Whisper itself.
A few things that you could try on the app today:
- Try with a different model (smaller or larger). This sometimes fixes some issues.
- Set the spoken language explicitly in Settings instead of Auto Detection.
- Prefer cleaner dialogue audio when you can to avoid background noise.
There’s no perfect switch for it yet though, Whisper can still loop sometimes.
