Thanks @grb, the team will be investigating the Github issue. For context, below outlines expected behaviour:
On your Local Machine
Data that is stored on your computer/device is encrypted and only decrypted when you unlock your Vault. Decrypted data is stored in memory only and is never written to persistent storage.
We also reload the application’s renderer process after 10 seconds of inactivity on the lock screen to make sure any managed memory addresses which have not yet been garbage collected are purged. We do our best to ensure that any data that may be in memory for the application to function is only held in memory for as long as you need it and that memory is cleaned up whenever the application is locked. We consider the application’s encrypted data to be completely safe while the application is in a locked state.
