Game Name?

Nicktoons Unite! (USA)

Game ID? (right click the game in the game list, Properties, Info tab)


MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)


What's the problem? Describe what went wrong.

When playing the game, there will be a rectangular blur present in the upper left part of the screen during levels (or a black box in older versions of Dolphin), and some sort of image corruption on the top and left edges of the screen.

What steps will reproduce the problem?

  1. Start the game
  2. Load a level (tested most heavily on "The Jellyfish Factory")
  3. The blur box/black box will be there in the upper left, and the image corruption will be on the top and left edges.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 5.0-10914 (in this version, the box is a blur effect)

Is the issue present in the latest stable version?

No, 5.0

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool and anyone who is building Dolphin on their own can use git bisect.)

First broken version is 5.0-6860 (here the box is black, but in the same place as the blur)
Everything works fine in 5.0-6858

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here:

Additionally included 3 screenshots:
- one working normally from 5.0-6858 (working.jpg)
- one with the initial black box appearance from 5.0-6860 (black box.jpg)
- one with the current blur box appearance from 5.0-10914 (blur.jpg) - you can see the difference between the blurred and non-blurred areas if you look at Jimmy's shoes and the large shadow on the ground next to him (Jimmy is the one with the swirly brown hair)

What are your PC specifications? (CPU, GPU, Operating System, more)

Win10 x64
GPU: Nvidia GTX 1080
CPU: Intel i7-6700K at 4.0 GHz
Computer runs at 1440p165Hz

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

I tried changing the internal resolution (lowering this just made the box bigger), disabling the widescreen hack and using the normal 4:3 aspect ratio, switching back to Synchronous mode (no Ubershaders) from Async Ubershaders, and the various backends, none of which worked.
I took a quick look at the commit for the first broken version, and it looks like this is directly related to removing projection hacks (the GNO ini file for this game is specifically modified).

FYI. Seems to work when you disable "Defer EFB Copies to RAM".

I just checked in v5.0-11050, and it has that option set to false in GNO.ini, but the issue is still occurring.

I swear I already looked into this issue once. I'll look into it again and see if I missed something.

Seems to occur in object range 334 to 351.
Was it an area for debugging/HUD left in the game for range in object range 334-349? It doesn't seem to align with any on screen HUD elements.
After objects 350-351 get added to the range we seem to go and get the EFB copies from RAM instead. Thus the blurry issue mentioned in the report.
