OS 2.7.5 --> sync and pitch issues?

[brambos]

After updating my TI Snow from 2.7.3 to 2.7.5 it seems I'm getting weird sync and pitch-slide issues in Cubase Studio 4.5.

Especially the arpeggiator seems to be problematic, and the timing issues seem to get worse when tweaking the knobs on the Snow's frontpanel. At times the audio can't hold its pitch and starts to whine as if a monkey is hitting the pitchbend stick...

Anyone else getting this? I didn't have it with the 2.7.3 OS version.
