What's the problem? Describe what went wrong.

[The Planar Reflection in Stage 103 (Beginner Extra 3) is missing, despite being there on real hardware, and being there in older versions of dolphin.]

What steps will reproduce the problem?

[In Dolphin version 5.0-13081 or later, either beat beginner without losing a life and get to Beginner Extra 3, or just use this AR code, HUEA-0C49-D4Z7Z
FP4C-4E4V-9BN0U, for the NTSC-U version, and go to stage 103.]

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


Is the issue present in the latest stable version?

[No, it's not present in 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.)


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:

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

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

Ryzen 3600
GT 1030
3600mhz 16gb ram]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Save state for version 13337 at stage 103 in the debug menu

[Every other planar reflection in the game works. The one on the sega logo, the ones in the other space stages, the ones in the storm stage, master, ice, they all work. This is the only one in the whole game that doesn't work anymore, and I find that intriguing as it also seems to be the most clear one; it's completely reflective. Call me crazy and unhelpful, but the fact this was broken on the update that fixed the debug cubes in sunshine that had to do with invisible stuff doesn't seem like a coincidence to me.]

I'd also like to note that I normally use vulkan, but I tested every single API including the software renderer, and the results were the same every time. I tried changing to cached interpreter, interpreter, interpreter + software renderer, messing with every EFB option under the sun and always had texture cache accuracy on safe.

  • Regression start set to 5.0-13081
  • Regression changed from No to Yes
  • Milestone set to Current

Thanks for the clear report with a bisect and FIFO log!

It looks like this issue (and #12379) were present in the software renderer prior to 5.0-13081 (and similarly the debug cubes already did not show up in the software renderer prior to 5.0-13081).
