I have noticed the same issue and I think this happens because someplayer doesn't use the media framework (which uses the DSP and seems to be quite optimized) but runs the playback on CPU only. A modRana can also tax the CPU quite a lot (rendering the GUI, downloading tiles at once, checking if you are on route during navigation, etc.), the might both fight over the (single-core) CPU, which might result in interruptions in playback.

On the other hand, if modRana is not the active application, it should do that much even when logging (no GUI rendering & no tile downloads) and the playback should be OK.

Ive optimized the logging quite a bit last summer, so it is not incremental and should be quite light on resources.

The maps were pre-saved so there was no internet activity going on (or does modRana check with the server for versions?).
If it can file the tiles locally, it won't do any online requests. You might also disable network usage completely in options->Network->Network usage.

So I would say - try the default media player and see if you have the same issues.

I have created white versions of mode images (bus, car, cycle, train, walk). I use them in night theme; they fit especially well into QML interface, since other icons (fullscreen, current position) are also white, not black.
Best wishes.
Nice, thanks !
I'll add them to the night theme + looks like I'll finally have to add theme switching to the QML GUI.

Maybe the DSP can't handle ogg so it is decoded by the CPU in both cases ?
