What's the problem? Describe what went wrong.

When me and a friend play the vs mode arwing only, the game begins to slow down tremendously. We've discovered after testing with each other that
the cause is when the screen is in view of the in game sun. Both maps we've tested, the space one and the great fox aerial battle, have a sun object
and when the camera looks at the in game sun the performance drops immediately. The game becomes unplayable as its almost at a single frame per second.
When we both are not looking at the sun and shooting each other, the game is fine. The moment we look at the in game sun it slows down immediately into an
unplayable state. It is important to note that this does not happen when doing the vs mode locally.

What steps will reproduce the problem?

  1. Go into the vs mode with net play.
  2. choose either the great fox map or the space map
  3. The game initially will run fine but when the camera views the in game sun the bug will rear its head.

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

IDK

Is the issue present in the latest stable version?

Yes 5.0-21460

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.)

[First broken version number here (if applicable)]

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

[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)

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

We have tried changing the rendering engine as well as running no audio to no avail.
