Emulator

Game Name?
Mario Kart: Double Dash

Game ID?
GM4P01

What's the problem? Describe what went wrong in few words.
Objects which are far away appear very blocky.

What did you expect to happen instead?
Objects to appear less blocky. I could swear it doesn't look this bad on the real console, but could be wrong.

What steps will reproduce the problem?

1. Start the game, mash the "A" button until you're ingame at the Luigi circuit
2. Drive around a bit, you'll see that distinct objects look really odd.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have

latest Dolphin version first.

4.0-3261

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Probably, I'd need to check
