don remember experiencing this with windows 8
Is it a pc problem ?
I have the same with this menu in Windows 7, NVidia GTX850m (mobile) graphics card Editor version: 4.18.2.
When you go into the tree by hovering over one of the options that expand, the menu that comes out is drawn twice. 1: the normal one, 2: the one over the parent menu, however this second one is flickering. There is also some other editors that flicker larger sections of their UI. Did you manage to fix it?
Seems to be an issue with laptop GPUs switching between intel and NVidia. They won’t fix it according to this issue: UE-20675

EDIT:
I fixed the glitches for myself by forcing “Integrated Graphics” on the editor in my NVIDIA Control Panel.
Executable path: “C:\Program Files\Epic Games\UE_4.18\Engine\Binaries\Win64\UE4Editor.exe”
It works for now, but might give performance issues while testing in editor. I haven’t stress-tested yet.
