Ok, can you edit/modify the .kodi/userdata/guisettings.xml and remove the <resolutions> node from it? Basically the following lines need to be removed.
<resolutions>

But copy the file before you do it so you can restore it afterwards 
?
The correct steps would be:
- stop kodi using
systemctl stop mediacenter - then edit that file mentioned above and remove those lines and save the file
- reboot
When the V comes back up try to reproduce that issue.
