@capc8m Please check our official Recalbox documentation:

If it still doesn't solve the problem, check if we don't already have an open issue in the Recalbox gitlab:
https://gitlab.com/recalbox/recalbox/-/issues
If there is already a related issue, please comment on it, otherwise, open an issue on the official Recalbox gitlab.
The Forum is very useful for exchanging information and clearing doubts, for other users to confirm if the bug really exists or if it's just some misconfiguration on the part of the user. But, when it is a proven bug, you should open an issue for better visualization by the developers.
