Hi Jira team. Recently I have download the new minecraft launcher and when I used it it worked good with my 1.8.1 minecraft version, which i had a survival map. When downloading minecraft 1.8.3, I opened the 1.8.1 map, and it worked well, but as soon as I tried to make a new survival map with the 1.8.3 version, it appeared me with missing/invisible textures and the tree logs black. I sended a picture to prove that it´s not like other bugs I have seen. Also, I tried to make more survival maps with all the official 1.8+ versions, but with no result.
Also after I opened the first 1.8.3 survival map I played with my old 1.8.1 map with a resource pack called sphax pure bdcraft with the 3D models, and I think that when I opened the new map it made the bug, but I dont understand why, before changing and re-installing minecraft didnt get well.

Hope you will find the solution, because I tried with both launchers, the first and the alternative for windows 7, making a backup of the .minecraft folder and making my render distance lower.

Thank you a lot,
Kevin
