What's the problem? Describe what went wrong.

On default settings the whole screen is purple.

Before 5.0-10000:
The game works regardless if "Store XFB Copies to Texture Only" is enabled or disabled.

After 5.0-10000:
The screen is purple if "Store XFB Copies to Texture Only" is enabled.

XFB Copies to Texture Only = Purple Screen.
XFB Copies to Texture Only + Immediately Present XFB = Displays Green bar at right side of screen.
XFB Copies to RAM(and Texture) = No Problem
XFB Copies to RAM(and Texture) + Immediately Present XFB = Displays Green bar at right side of screen.

Before 5.0-10000 you could therefore Use default settings without graphical issues allowing use of higher internal resolution.

After 5.0-10000 default settings displays purple screen. Changing graphic settings to solve both issues means enabling XFB Copies to RAM(and Texture) which limits the resolution to looking like native.

What steps will reproduce the problem?

Run the game. The effect is at always present so you do not have to progress in game to see the issue.

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, 5.0-13495

Is the issue present in the latest stable version?

No, 5.0

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.)

5.0-10000 -> https://dolphin-emu.org/download/dev/18589e50ab44957f4955596ac238d900f28959c3/

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

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

Ask for more fifologs or screenshots if required.

This is likely the texture cache failing in some way, as evidence by it locking itself into 1x internal resolution.

The bisect, while it looks funny pointing to an even number, appears to be reasonable - https://dolphin-emu.org/download/dev/master/5.0-10000/
