Emulator

I've been seeing a possibly similar psychedelic textures in other games...
Metroid Other M (post loading a save game)
Mario Kart Wii

Example of the issue in Mario Kart can be seen here...

That has nothing to do with this issue, I believe MaJoR knows more about that one.

This one has to do with the render to texture that OoT does for the pause menu acting weird if you change pretty much any graphics setting at all while you're playing. It also doesn't work on the first pause; ends up grayscale.

kostamarino: Is this issue still valid on the ogl-tex2d branch?

Yes, and i also get crashes when pressing start now.

Used dolphin-ogl-tex2d-4.0-453-x64 from https://dl.dolphin-emu.org/builds/

Changing internal resolution flushes both texture cache and the current efb content, so it's because we lost some data there.

This issue does not seem to be happening anymore in Dolphin 4.0-595 (re6676b456535)

Please confirm, kostamarino.

Hmm, i still have it so perhaps there is something else at play here. Bad dump or old drivers perhaps? I will have to look into it.

Not really a texture cache bug. D3d is fine, only opengl is broken.

Steps to reproduce:

1. Use opengl
2. set efb2ram and real efb
3. load the game, pause, check the equipment screen
4. unpause or not
5. Change the IR via hotkey
6. pause or unpause and then pause(depending on 4)
7. Colors are fun

This happens with fast and safe texture cache accuracy btw.

i meant xfb of course

This is also affected by CPU/GPU sync – on my low-end hardware (i3-540, Radeon HD 4670, subpar OS X graphics drivers), the EFB to RAM + medium texcache + no Scaled EFB Copy combo didn't help any until I tried single-core mode. (First pause is still greyscale for two seconds; not gonna bother checking if RealXFB fixes that because it otherwise works flawlessly at 3x IR.)

With efb2ram and real xfb, i'm not having a gray screen issue at all, neither with opengl nor with d3d. But i can reproduce the psychedelic colors by changing the IR via hotkey when using opengl.

PS: Is anybody else having the nintendo logo not at the center of the screen when using opengl? For me it's shifted a bit to the right when using opengl, with d3d it's in the center(left/right). On PAL it's maybe easier to notice, because of the 60Hz only message on that screen.

Fixed by various EFB2Tex changes. EFB2RAM is required, but changing IR/EFB2Tex/Texture Cache settings no longer breaks it.
