[Performance Issue] UV editor increasingly lowers performance the more faces are displayed

[Azagwen]

What are you trying to do, and what do you expect to happen?

I'm editing the UVs of a mesh, with a medium number of faces.
And I'm trying to navigate the UV editor panel smoothly to move UV islands & paint

What happens instead?

When UV overlay is enabled, zooming and moving elements is significantly slowed down

When UV overlay is disabled however, this section gains a significant boost in performance, but now I have no idea if the faces I'm moving may be overlapping with another element.
And moving a set of faces still happens at a relatively low frame rate.
