Since I upgraded to Unity 5, I have suffered from a problem where the objects in my game world have a white outline (both in the editor, and in build versions) - shown here: After hours of trawling the internet, I came across the suggestion of disabling anti-aliasing within the Unity quality settings, and the ugly white lines disappeared entirely (see second screenshot): Of course, this is not a good long-term solution, so I want to get to the bottom of it.Importantly, I have seen this on several occasions when I am playing games, where it is also most evident on trees. This would suggest to me that the fault may lie in my GPU/GPU drivers. All video drivers are fully up to date. I would be extremely grateful for some feedback on this. Perhaps it is just a faulty GPU, but knowing this for sure would at least be a start. Thanks!
