Description

Game Name?

Luigi's Mansion

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

GLMP01

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

109274d9078b5aecf3bfa9af1d10688c

What's the problem? Describe what went wrong.

Inside the mansion there are graphical problems with the shadows.

What steps will reproduce the problem?

Start the game and start a new file. Do not skip the intro cutscene. While the second cutscene ended, try moving around and turn off the flashlight with the B button and you'll see the graphical problems with the shadows. Depending on the backend you can also see the shadow issues without turning off the flashlight by looking at the light from the flashlight itself. I think it's gonna be much more consistent if you press random buttons while the second cutscene plays

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

5.0-14435

Is the issue present in the latest stable version?

Yes I tested it on 5.0 too

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 https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds 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: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

(Look closely at the flashlight)

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

CPU: Intel Core i5-7360U 2.30GHz
GPU:Intel Iris Plus Graphics 640
RAM: 8GB
OS: Windows 10

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

This graphical issue doesn't seem to happen in NVIDIA GPU's. Not sure if this also occurs on AMD

I'm also using the latest stable drivers from Intel

Fifolog is no longer available.

I see. Seems like I'll have to look and see if I can reproduce this again and reupload the fifolog

Here's a fifo log!

  • Subject changed from Graphical issues on Intel GPU's to Luigi's Mansion: Graphical issues on Intel GPU's
  • Status changed from Questionable to Accepted

Confirmed on the Vulkan backend with that fifolog. Renders correctly on NVIDIA GeForce GTX 1650 Ti, but has the broken shadow on (integrated) Intel(R) UHD Graphics.

I'm not sure if this is fixable. In the first frame of that fifolog, the broken objects are 65 and 70. Here are the matrices for object 64 (which is fine):

XF register Write 12 XF mem words at 0000
Position matrix row  0 col  0 = -0.18265045
Position matrix row  0 col  1 = -0.90213823

and here's the matrices for object 65 (which is broken):

XF register Write 12 XF mem words at 0000
Position matrix row  0 col  0 = 9044000
Position matrix row  0 col  1 = 14660088000000

Normal matrix row  2 col  1 = 6.4780067e+19
Normal matrix row  2 col  2 = 9.8983287e+36

These values are complete garbage, and result in extremely large positions far beyond the top and bottom of the screen. It seems like NVIDIA just rejects these as nonsense and draws nothing, but Intel is perfectly willing to draw it, resulting in the lines.

Without actually owning Luigi's Mansion I can't determine exactly why these matrices are garbage, and if it's an emulation issue or just how the game works.
