It actually worked fine before 3a7cd4e8736313befb3db3323c86f834a404f9c0 and last worked on b34fe2b8f1915d5ec46db26362d2e59062e6c240

Your bisect makes no sense, please try again on it.

It is an issue with virtual xfb and pal region that causes a subtle shaking so he first noticed it after the gameini update. Perhaps finding the build that causes the shaking with virtual xfb in pal region is more useful, although i think there should be an open issue about it.

it just enabled virtual xfb which caused the issue

Try RealXFB then.

Sorry, It crashes after the logos

By it JMC4789, I mean RealXFB

I'd rather figure out this issue than the silly Virtual XFB stuff. Post a coredump please.

Gives segfault after logos when ran from Terminal in Linux if you enable RealXFB after you start the game and dumps core but I don’t know where to find the core dump

Baten Kaitos PAL version suffers heavy flickering all the time with virtual xfb enabled. Virtual xfb is forced by the .ini file. Before 4.0-4824, it was flickerung between picture and a black screen, in both d3d and opengl. After 4.0-4824, it's flickering between the picture and an offset picture in d3d.

Changing IR changes the size and position of the offset picture.

This might be related to fbheight?
\Source\Core\VideoBackends\D3D\Render.cpp
in Renderer::SwapImpl
fbWidth is passed with the value 542/543.

Tales of Symphonia PAL reports 536/537 there, and is also flickering with virtual xfb.

Baten Kaitos has a small black bar at the bottom:

Tales of Symphonia does not have a black bar though.

FIFO logs for Baten Kaitos PAL and Tales of Symphonia PAL:
https://drive.google.com/file/d/0ByQgqzsPdirYY3p2WW1panJpaWc/view?usp=sharing

The logs were recorded in single core, with efb copies disabled, 3 frames, each game with virtual xfb and without xfb. When playing them back with virtual xfb enabled, all of them just show a black screen. When playing them back without xfb, they look like they are supposed to.

thanks for the logs. I'll fix this later today I think another issue I'm working on has the same issue. These logs will be useful.

Nobody can play back fifologs with XFB so can you tell me if a build from maybe 3.5 or 4.0.2 crashes with RealXFB?

Real xfb results:

On 4.0-4980 Baten Kaitos gets into a loop with Warning, Invalid Write to to 0x90b4fec0, PC = 0x80026504, then the values increase and eventually it crashes.

On 4.0-4980 Tales of Symphonia gets Warning, Invalid Read from to 0x10801088, PC = 0x800f7eb0, then 0x10801084, PC = 0x800f7eb0 and then it goes to a black screen without sound, and Dolphin can(!) be shut down normally.

On 4.0-1 Baten Kaitos gets Warning, BackPatch: Currently only supporting reads. Attempted to write to 90b4fec0. Then Warning, Backpatch write - not through EAX and then it crashes.

On 4.0-1 Tales of Symphonia goes directly into its black screen, see above.

3.0-749 does the same as 4.0-1.

Thank you for that. Then I don't think the realXFB issue I'm working on is the same.
But I'll fix the virtualXFB issue anyway.

And can you tell me MMU ON with openGL in Interpreter no changes to behaviour with realXFB?

The above tests were made with d3d.

Interpreter + OpenGL + MMU just outright crashes both games with real xfb. With JIT + MMU, there are no warnings, but both games still don't work with real xfb.

What about trying Interpreter + OpenGL + MMU back in 3.5?

In 4.0-1 Interpreter + OpenGL + MMU + real xfb, Baten Kaitos still crashes. And in 3.0-749 i don't even know how to enable MMU. I'm not sure if MMU was even actually operational before Fiora's fixes.

OK so I got all my games back from my old home so I could look at this further.
The crashing with realXFB must only be NVIDIA since I can't replicate.

But this game has a few separate issues one D3D specific so it's gonna take another little while. I didn't have much freetime in the last week to look at XFB issues.

I have a Radeon HD 7790. What GPU do you have? Also, do you have PAL or NTSC games? I think all mentioned issues are PAL only.

Yeah I have PAL and can reproduce everything but the crashes.

I have an AMD R9 290 I just assumed the realXFB crash was because I thought you had NVIDIA nevermind on that assumption then.

I have a fix in mind I'll commit it to my PR tomorrow.

Well, if it doesn't crash on your system, but on mine, it's either user error or a driver problem. So it doesn't matter. Thanks, i look forward to it, but no need to hurry.
