This happens whenever I try to do /smpx to get to another smp. I have reinstalled minecraft twice and updated my computer, anyone know what is going on? http://imgur.com/a/M11Dz
I don't know what it is, but whatever is it is, it is absolutely crazy Have you tried to update the drivers of your graphics card ?
Go to your .minecraft folder. Back up saves, resourcepacks, mods, etc. Delete the .minecraft folder. Launch Minecraft. Let me know if this works.
Have you tried removing your resource pack? I have found many that can cause graphical glitches. EDIT:If you are using a 1.9 resource pack then that is most likely the issue. What resource pack are you using?
I'd agree with the graphics card dying, but there's a chance something else is messing with the video buffers. Maybe tweaked your graphics card settings or upgraded video drivers just before this? It's interesting that the buffers partially render. Maybe there is hope.
