It looks like this:\r\n\r\n![Blue pixels bug](https://i.imgur.com/qQVbz20.png)\r\nhttps://i.imgur.com/qQVbz20.png\r\n**Important**: Watch the image in full size, otherwise the problem may be hard to see.\r\n\r\nThese pixels appear to have the same color as the sky.\r\n\r\nWhen I look around (i.e. move the mouse) the pixels start to flicker, i.e. there will be pixels on other positions. When I stand still, the pixels stay. The pixels may be easier to see in darkness, shadows or at dark walls. Interesting observation: If you manage to get the camera back to the EXACT position, you will see the exact same pixels again. So it appears your viewing angle matters a lot.\r\n\r\nThis screenshot has been taken in c67f2b29651eb98aaaf14649560d91ce5963223d. I first have completely reset `minetest.conf` and then disabled shaders in the main menu. I run Minetest on GNU/Linux with the OpenGL backend. (**EDIT**: No idea if shaders are responsible.)\r\n\r\nI've seen this bug in 0.4.14 and c67f2b29651eb98aaaf14649560d91ce5963223d, but if I can remember correctly I have observed this bug since the dawn of time (probably). ;-)"},"comment":{"url":"https://api.github.com/repos/minetest/minetest/issues/comments/268194824","html_url":"https://github.com/minetest/minetest/issues/4912#issuecomment-268194824","issue_url":"https://api.github.com/repos/minetest/minetest/issues/4912","id":268194824,"user":{"login":"Zeno-","id":5899883,"avatar_url":"https://avatars.githubusercontent.com/u/5899883?v=3","gravatar_id":"","url":"https://api.github.com/users/Zeno-","html_url":"https://github.com/Zeno-","followers_url":"https://api.github.com/users/Zeno-/followers","following_url":"https://api.github.com/users/Zeno-/following{/other_user}","gists_url":"https://api.github.com/users/Zeno-/gists{/gist_id}","starred_url":"https://api.github.com/users/Zeno-/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Zeno-/subscriptions","organizations_url":"https://api.github.com/users/Zeno-/orgs","repos_url":"https://api.github.com/users/Zeno-/repos","events_url":"https://api.github.com/users/Zeno-/events{/privacy}","received_events_url":"https://api.github.com/users/Zeno-/received_events","type":"User","site_admin":false},"created_at":"2016-12-20T09:24:29Z","updated_at":"2016-12-20T09:24:29Z","body":"This has happened ever since I've been involved in Minetest.
