When will scrolling performance in Br 13-15 be restored??

When will scrolling in Br 13-15 be restored to the performance of V12?

You never seem to want to answer this, why is that?

So, please answer.

1. Do you know whats causing the horrible performance in 13 and newer?

2 CAN you restore the speed to V12 when it comes to scrolling, moving and everything in the content window / panel? 

3. If so, are you working on it, since it should be No1 priority?

4. If not, why are ypu not talking about this with us?

Cant you see that a lot of people are talking about this and want answers? Bridge isn't usable with the slow performance and new features arent needed as on now.
