Ue4 bsp brush temporarily disappears while moving

Hi, brand new to UE4 looking to see how it compares to unity having used that for many years.
Just starting off with the basics and i’m noticing and odd thing while using the BSP Brushes

The brush temporarily disappears while moving blocking out this is really annoying as I cant see whats causing it
and seems to get worse if I scale objects up


Does anybody know the reason why it does this in the view port?
Is there any setting I can change the fix this? I have a pretty good setup for 3D but could it have anything to do with my system spec?

My PC spec is:

AMD Ryzen 7 1700X Eight-Core Processor, 3400 Mhz, 8 Core(s), 16 Logical Processor(s)
AMD Radeon ™ Pro WX 7100 Graphics (ruuning with the latest drivers)
Win 10

Runs Maya, Unity, Substance, After effect with no issues at all.
