When I clicked on the launcher, the first thing I noticed is that the text and images on the "Update Notes" tab is all messed up. However, the launch logs and profile editor tabs are alright. Thinking it's just the launcher, I opened Minecraft and found that the main menu, options menu, singleplayer menu, multiplayer menu, and Realms menu were just as messed up. I don't know what may have caused this glitch, as nothing adverse happened the last time I opened minecraft. Attached are screenshots of the issue on version 1.9.
