Texture errors found in debug console (Mario Party 5)

So I decided to play this game in Dolphin (used 4.0.2 for the game) and I decided to "mess" with the debug console. I notice a huge slowdown when emulation starts (slow movement, stuttering graphics). I looked at the console and found this:

I would be happy with any explanation about this thing. Specs on profile.
