What's the problem? Describe what went wrong.
When I switch the backend from OpenGL to Vulkan, the graphics and textures don't render properly even though it has better performance than OpenGL in terms of frame time.
What steps will reproduce the problem?
On Android, set F-Zero GX GPU backend from OpenGL to Vulkan. Store EFB to textures only and dual core are enabled, on latest development build. Compile shaders before starting and Hybrid Ubershaders are turned on too.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
5.0-21383
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
[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]
What are your Android Device specifications? (CPU, GPU, Operating System, more)
Device: Retroid Pocket 4 Pro (D1100)
CPU: 478@2.6GHz 4A55@2.0 GHz
GPU: G77 MC9@836MHz
RAM: 8GB LPDDR4x
Storage: 128GB UFS 3.1 + TF Card Slot
OS: Android 13
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

According to https://bugs.dolphin-emu.org/issues/8713 F-Zero GX has problems when dual core is enabled. Try disabling it and see if that fixes any of the bugs you're seeing.

I just did it but after disabling Dual Core for F-Zero GX, the same graphical issues on the Vulkan (not OpenGL) backend are still present, just like the screenshots but I get worse performance for F-Zero GX on Vulkan which becomes a lot worse for OpenGL without dual core enabled. The graphical issues only happen on Vulkan (and not OpenGL) on both 1 and 2 cores but OpenGL is still slower and worse in performance than Vulkan.
Oh yeah, on this part of the filed bug report:

I failed to mention that I set my Retroid Pocket 4 Pro to "High Performance" mode with the fan mode set to "Smart" so that will added onto that part of the question. But even after all the performance and fan modes, the same graphical issues occur on Vulkan, even with dual core disabled.
