Hi,

I'm having a very minor issue with the notification\toast not updating while cycling trough subtitles or audio languages. The toast only updates when it disappears. It does not update the text when I cycle trough the subtitles multiple times. No difference during playback or pause.
This used to be smoothly on PI2. I tried setting the 'Limit GUI updates during playback' to unlimited but that didn't do anything differently.

In the same screen there is an option 'Allow hardware acceleration - OMXPlayer' but that doenst do anything for this minor problem as well. (btw, what does this do? I can't find any documentation on this)

Any ideas of what I am doing wrong? The rest of my XBian install is pretty much default.
Toasts\notifications of other addons are updating fine.
