Issue – Kodi only occupies a quarter of the screen



Up until yesterday there were no problems, but since today when Kodi is running in 4k resolution, the image only occupies a quarter of the screen, the top right corner. I am attaching log files and a screenshot.
Additional details:
Kodi version: 20.2.0
Device: Raspberry Pi 5
Operating system: LibreElec 11
TV model: Sony 65A75K

Steps to reproduce the issue:
Launch Kodi
Set the display resolution to 4k
Observe that the image only occupies a quarter of the screen

Attached files:
Kodi log file

Please let me know if you require any further information.

Additional notes:
I have tried restarting Kodi and my device, but the issue persists.
I have also tried changing the zoom and scaling settings in Kodi, but this does not resolve the issue.
I am able to watch 4k videos in other media players without any problems.
