Freezing web interafce

Hi folks!

After some songs played without any issues, web interface stops updating - shows last song artwork as well as last song duration on the left “donut”. Sometimes it stays in such state for one song and refreshes again with the third song. Sometimes it refreshes to correct artwork just a moment before song’s end. If I change volume, it updates artwork, played time and volume immediately.

The same behaviour is on web interface as well as on local RPi ( modified to display all the time without going to sleep ar screensaver).

Any suggestions how to keep display updated all the time?
