BUG: DOP window grows in size

Hello,

with the new version of Nuendo 15, I experienced an odd behaviour of the Direct Offline Processing (DOP) window and the “SPL Transient Designer” plugin by Plugin Alliance. Everything was working totally fine under Nuendo 14.

First, the DOP window creates a lot of empty space around the plugin:

The empty space even grows in size each time I re-select a clip with that plugin applied:

Strangely this only happens with the “SPL Transient Designer” and all other plugins work just fine. I already contacted Plugin Alliance about this, but they said it is a Nuendo issue, which makes sense, since all of this just started with Nuendo 15 and has not been the case with Nuendo 14.
