I have minecraft version 1.7.10, and I had downloaded sphax pure bd craft (resource pack) and biomes o plenty (mod) and installed them both at about the same time, then started playing and noted that it caused blocks and thumbnails for items (blocks, weapons, other stuff) to flash and sometimes even at the right angle or if you mouse over them they'd have random other textures momentarily. It happens a lot when you open your inventory, but just moving around has things just flashing / spazzing out. So I deleted .minecraft folder, and started over, installed sphax pure bd craft, BUT, then I just tested it out, and I think it isn't the resource pack that's doing it, but the mod (biomes o plenty) that is spazzing out.
What could be causing this?
EDIT: I just reinstalled, without installing any mods or resource packs... and still getting the issue.
Not sure what to do in this case? Downgrade my client perhaps?
What can I do to fix it?
I really like biomes o plenty, so I'd like to keep it if possible.
