Short description of error
Ctrl + Middle mouse zoom in viewport while rendering cycles is really laggy while renderborder is used. (Problem only occurs while camera is activated)

Tested this in several scenes, seems like this behavior started with 2.8

Event Timeline

Sebastian Parborg (zeddb) lowered the priority of this task from 90 to 50.

In 2.8 this seems to stall the viewport when refreshing the cycles render. In 2.79 only the content in the render border lagged behind.
@Brecht Van Lommel (brecht) bug or not?

Worth investigating where this comes from, even if it's not high priority.

I also noticed, that cycles in viewport was much smoother with 2.79. Looks and feels like the refresh rate has changed.
Maybe this is also the reason for the camera zoom lag.
