Upon getting 50 Fury and when using empowered attacks or Dominus, there appear to be missing textures indicated by blue boxes.

When hitting 50 fury, blue boxes surround Renekton's forearms.

Using 50 Fury Cull The Meek has a trail of blue boxes inside the swing.

When using Dominus, blue boxes swirl around inside the aura in addition to the normal sand particles.

Enabling/Disabling Colorblind Mode has no effect on the boxes (or their color).

Have not tried on lower than Very High Graphics settings.

The skin isn't finished yet so the blue boxes are missing textures. No need to worry :>

A few days ago with this new skin, I noticed that occasionally you couldn't recall after using abilities at times, the way to fix it was by activating another ability. I do not know if it was fixed already, and if not I assume it will be fixed by the time it makes it onto the live server.

I didn't notice the recall bug mentioned but I did notice the texture bug showing dark boxes during certain animations such as his ult and his cull the meek.

I have noticed this as well with his q letting off little boxes lol

All the new skins i sometimes cant recall, but that was on the day they were released.
