Emulator Issues #12203
Vulkan API changes display refresh rate when going into Full screen
NSMBWii, but others as well.
Game ID? (right click the game in the game list, Properties, Info tab)
MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)
What's the problem? Describe what went wrong.
When I have Vulkan back-end enabled, and when I select Full Screen, my display refresh rate changes from whatever I set it as, to 59.34 or there about.
It also causes my Media Player Classic to stutter when trying to play a video file on full screen, and it gets fixed when I change the refresh rate in advance settings. It sometimes, when selecting Full screen, changes the HDMI Scaling to 0%.
This only happens with the Vulkan back-end, never when Open GL is selected.
I have also tried a different game built on Vulkan API to see if it has anything to do with Vulkan and not Dolphin, and there are no issues.
What steps will reproduce the problem?
Open NSMBWii with Vulkan API, and go to Full Screen.
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?
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
[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)
AMD Ryzen 2700X
Windows 10 PRO 19041.388
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

If the display refresh rate is changing to 59.94, that's actually the correct refresh rate for GameCube/Wii games. I'm surprised it is doing it automatically, though.
I'd need someone with GPU expertise to confirm what we can do about this, though.
