Black or noisy turning pages animation in Valkyria Chronicles II (ULUS10515_1.00)

[justafella]

What happens?

While going through the pages of the Yearbook (or anything with pages to turn) in Valkirya Chronicles II (ULUS10515_1.00) the turning pages animation becomes all black or noisy. Not something to keep me or people from playing but I thought I should report anyway.

What should happen?

Pages should look like they are.

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

• Windows 10 64 bit;
• Acer Aspire ES15;
• Intel Celeron QuadCore N3450;
• Intel HD Graphics 500 (driver ver. 27.20.100.8476);
• ppsspp-v1.10.3-470-ge8779fdc8-windows-amd64

Additional Info

• Tried all the backends but none displayed the turning pages correctly;
• Tried different rendering resolutions;
• Tried turning on/off other options like Mode (Non-buffered & Buffered), Simulate block transfer effects, Vsync, Hardware transform, Software skinning, Hardware tesselation, Anisotropic filtering.
• I have recorded what happens and I have made a save state. If there is any way to make them available for you to take a closer look, just tell me.

P.S: I searched around to see if this issue had already been reported. I'm sorry if it turns out to be a duplicate.

Tested the latest build and the issue persists if going back and forth the same page. Also, the pages don't look noisy anymore, but all black.

Ah, okay, the rest of this is caused by depth texturing.

Basically, we end up with no framebuffer attached, but also the texture released by ReleaseTexture in AttachFramebufferValid or AttachFramebufferInvalid.

Attach framebuf and release tex: 04114000
Creating FBO for 04114000 (z: 04088000) : 256 x 256 x 0
Saved safe size (256x256) 04114000 to 04134000
Decimating FBO for 04114000 (256 x 256 x 0), age 6
Detach framebuf (tex now dead): 04114000

The reason? It xors the hash twice, making it all the way back to the original hash and preventing rebuild.
