Emulator

Try using XFB2RAM in the hacks tab.

Try turning off dualcore now

Turned off dual core and nothing changed, still seeing the black flickering bars during all the stuff before the title screen.

Please bisect then, I don't remember this happening.

Tried using the bisecting tool, but that didn't work so I started manually going through the builds and I noticed that from the stable version of 5.0 all the way up to 5.0: 5833, after the save stuff, everything just goes all black (Doesn't crash, there is still sound and it's going on) until it hits the title screen and everything goes back to normal.

I believe I narrowed it down to 5.0: 5874 cause not only did the intro stuff finally started working again, but those annoying purple bars returned too.

Probably can turn on immediate presentation to return the behavior to how it used to be before the videos started playing.

I can confirm that if you turn on immediate presentation for both 5874 and the latest dev build, everything in between the "Save load" and the title screen go completely black.

I found out that if you jack the emulated CPU clock up to 400%, for some reason it stops freaking out.

Yep, overclocked it to 400% on both versions and it suddenly appeared normal, I also noticed that the only backend that doesn't have issues with this is the software renderer

It's probably a texture cache issue of some kind but I have no idea what would cause it.

I tracked it down to 5.0-146 -> https://dolphin-emu.org/download/dev/7ee6d082131cf40b8a8471ff3ac967e30326f59e/

(To see the issue you will need to use Real XFB)

Phire explained that this is changing XFB settings during the frame, so we need to implement a new feature to recalculate things at the end of the frame. Will add some latency, but appears necessary in this game. It would be optional and only affect this game.
