Description

What's the problem? Describe what went wrong.

This also happens in the Memory Card screen in the Gamecube Bios, and sometimes when pressing the home button on a WiiMote mid-game.
Certain graphics have a flickering checkerboard pattern when the game in played using the Vulkan or Metal backend (although it happens less using Metal)

What steps will reproduce the problem?

Use the Vulkan backend. Certain graphics like the mini map will flicker.

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, 18501

Is the issue present in the latest stable version?

Yes.

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

I'm also attaching screenshots of the Gamecube BIOS because it's easier to see.

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

2.3 GHz Dual-Core Intel Core i5, Intel Iris Plus Graphics 640 1536 MB, macOS 13.2 Ventura.

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