RH 6 Performance in Layout View Slow

When im working in layout and the detail views are put to display modes like rendered or technical drawing the layout performance is relativ slow. Moving textblocks or annotations are very sluggish.
If i change all viewport modes to wireframe everything is smooth.
Is there an workaround to speed this up or ist this a generall Rhino problem?

Im Working with RH6 on a Win 10 Syste, with an Geforce GTX 1050 and an i-7700. So i think there is enough Performance on the hardware side.
