For some reason, highlight outlines do not show up at all when I am using Roblox studio. This also includes the selection highlight that appears when you hover or select a part. The highlight fill color also has a weird texture that’s more noticeable the more transparent it is (See image below). This has been an issue for a while and I don’t see anything in studio settings that might’ve disabled highlights for me.
uhm, the part has a grid, when i scale the image up the part has a 1 pixel grid. 
hopes someone understands
