When player is facing a certain direction the blocks (most not all) are "ghosting" themselves as seen in the screenshot below. not sure what is happening or if its been reported already.

BackTools is the issue

I am currently only running mekanism and all modules

*edit - on minecraft 1.7.10

Strange. Are you sure you aren't using Optifine?

yea ive done a little troubleshooting. i started with quite a few mods installed. then i redownloaded my mc and only installed forge and mekanism. its a strange bug i do believe. im going to keep working on it.

This happened constantly to me in 1.6.4 and I just started experiencing it in 1.7.10 myself, but only after I started placing some mek machines. I've never used optifine or back tools. The only thing I do use that even mentions rendering is smart moving and its associated apis. I'lll look into it more.

no luck, complete uninstall and reinstall and only mods to touch my .minecraft folder are forge and mek
