Wavelab 10.0.40 GUI less sluggish with plugins

Sorry if this is another thread on an already discussed topic, but I couldn’t find the previous threads so I started a new one.

I also suffered the problem, that the GUI in Wavelab Pro 10 would almost freeze up as soon as I open a plugin window. The plugins I use are those most common in the industry - Waves, Sonnox (Sony Oxford), Plugin-Alliance, UAD, iZotope, McDSP, IK Multimedia and more. I’m running a 2013 Mac Pro (so it does have a GPU) with 64GB of RAM and Mojave (10.14.6).

I tried the latest version and for me the latest Version (10.0.40) does bring some improvements here. Waves plugins especially seem to work better for me now, which is a great, iZotope also seems to work. I still need more time to find out, if a combination of clip, track and master plugins will affect this.

What still does not work for me are the Sonox plugins (Sony Oxford) and anything McDSP. As soon as I bring the limiter or the EQ up the GUI is back to almost frozen - it gets updated may twice a second then. Is there any hope for these in the future - or any kind of feedback I could send to Sonox? Their plugins are especially useful in mastering.
