Hi Thorsten,
We will investigate and reply soon.
While waiting there are a couple of documents to review in case you missed them. They are listed at the end of the datasheet:
DRV8711 Decay Mode Setting Optimization, SLVA637
DRV8711 Quick Spin and Tuning Guide, SLVA632
Please take a look at your current waveforms. You may find that the decay setting is not optimized for your motor/system voltage combination?
