When I’m adding and selecting BSP geometry - selected object face and edges are flickering. First I thought I have issues with my video adapter, but now I see other developers also have this problem (on twitch streams, even in official tutorial videos). I just found solution, on only one page (https://answers.unrealengine.com/questions/597363/bsp-geometry-wireframe-flicker.html) and bug report (Unreal Engine Issues and Bug Tracker (UE-30764)).
But it’s strange for me, that this issue so unpopular. I don’t have seizures, but still, it’s almost physically painful to watch, to the point of impossible to work with this. I understand, that it is hart-to-fix bug (as stated in bug report notes), but may be it could be some workaround? Turning off Anti-aliasing or Realtime - helps. But for newcomers like me, it may be difficult to find solution, and, as I understand - setting layout in BSP first is essential part of level design. May be it makes sense to turn-off Anti-aliasing (or Realime) by default (or turn it off automatically when BSP is selected). I’m not sure, I just wanted to remind of this issue, because I think it can be important for newcomers, who doesn’t know how to fix it and if it’s even possible.
