Non-linear seek bar pointer movement issue in UPnP playback

Hello Tiki,

I’ve encountered an issue during UPnP playback.
If I pause the UPnP renderer for a period of time and then resume playback, the seek bar may behave abnormally.

For example:

• Current displayed position: 0:03
• (after waiting about 5–10 seconds)
• It suddenly jumps to: 0:10

In other words, the seek bar pointer does not move linearly with time progression.

So far, the only workaround I’ve found is restarting TuneBrowser.

Could you please help confirm whether this behavior is expected or investigate the cause?

Thank you very much for your excellent development.
