What's the problem? Describe what went wrong.
Disabling "Scaled EFB Copy" when using Vulkan and increased internal resolution (e.g., 2x), the map becomes garbled. The end result is similar to that of turning on AA when using native resolution.
What steps will reproduce the problem?
- Set backend to Vulkan
- Increase internal resolution (e.g., to 2x)
- Disable Scaled EFB Copy
- Boot up the game, create a new quest log. When gameplay starts, you'll be able to see the corrupted map.
- Map seems to remain corrupted in all other areas of the game

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.)
[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)
Tested on an Asus Rog Ally (AMD Ryzen Z1 extreme, 16GB Ram) and on a Thinkpad T480 (Intel integrated graphics, 32GB Ram). Windows 11 on both
Exact same problem with both machines. So probably not a driver issue.
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
