UE 5.4 - Strange Blue Line Artifacts in Game Viewport

A strange rendering issue (glitch/artifact?) in Unreal Engine 5.4. I didn’t have this issue on the previous 5.3 version. I’m assuming it’s related to my platform and rendering hardware?

This was run on a MacBook Pro M2 Chip with Metal v3.0 set as the shader target, however the different Metal shader versions didn’t seem to change anything. This same bug happens on new template projects as well, so it wasn’t something to do with the project itself.

Anyone else experiencing this??
