Edges on selected objects flickering

Hello everyone,

Strange thing going on with UEd4 here that I don’t recall ever seeing before.

Basically, if I have an object - like a sphere or cube - selected from the ‘Geometry’ tab (CSG brushes), the yellow outline around the faces has this fast blinking/strobing effect. Everything is otherwise performing/behaving fine, but that strobing/blinking is going to give me a headache if I have to work with CSG stuff for any amount of time.

I have a NVidia GTX970, driver version 384.76, which is the current one.

Anyone have an idea of why this is happening, or if there’s some setting I can change in the editor to prevent that?


I have the same issue. I’m running an NVIDIA GTX 980M. Updating the driver to see if that solves the problem.
