Question 1

Why does Thaluna require 100% Windows display scaling in real-time mode?

Accepted Answer

The standard real-time capture window depends on DPI and coordinate mapping between the overlay and the captured screen region. At scaling values above 100%, Windows and Qt can report logical and physical pixels differently, which can offset the captured region even when the window looks correct.

Question 2

How do I use OpenRouter in Thaluna?

Accepted Answer

Create an OpenRouter account, generate an API key, paste it into Thaluna under Settings > Ollama/Cloud, choose a model, and then select OpenRouter as the translation source in the language selection window.

Question 3

How do I connect a local OpenAI-compatible API?

Accepted Answer

Start a local OpenAI-compatible server such as llama.cpp, set Thaluna's Custom Local API base URL to the server URL, keep the API key empty unless your server requires one, and choose Local API in the translation model selector.

Question 4

What should I do if Thaluna crashes or OCR fails?

Accepted Answer

Use the Diagnostic build, reproduce the issue, and copy the console output when reporting the problem. For OCR instability, test CPU OCR first to separate hardware acceleration issues from general OCR behavior.

Question 5

Does Thaluna work on low-end laptops and RTX 5000 GPUs?

Accepted Answer

Thaluna works on low-end laptops using CPU OCR, while RTX 5000 series GPUs currently require CPU OCR for the built-in OCR backends due to upstream framework limitations. Translation can still be handled through Ollama or OpenRouter depending on your setup.

Question 6

Why does Audio Translation detect audio but return no text?

Accepted Answer

Check that the selected loopback device is the one playing audio, raise the application or system volume, confirm your OpenRouter API key and credits, verify STT model availability, and set the source language when possible. Very low source volume can trigger audio activity while still returning empty transcription text.
