What's the problem? Describe what went wrong.

After 5.0-5745 ( PR6118 - https://github.com/dolphin-emu/dolphin/pull/6118 ) Michael Jackson The Experience suffers from some stuttering: the stuttering doesn't seem to be random, because it happens always in the same moment/place of the game and the only way to avoid it is to enable "GPU Texture Decoding" option in the hack section of the video plugin, but this works only for OpenGL and Vulkan, because Direct3d doesn't have such option.

What steps will reproduce the problem?

Easier way to reproduce is to play for example the song "Heal the World": in the very beginning, when the camera scrolls down after some seconds you'll notice a brief stuttering (frames go down from 60 to 40-50 and then come back); another time where the stuttering is always present is in the song "Smooth Criminal", when Michael launches the coin you'll always have a brief stuttering and also at the end when he uses the machine gun you get the image stuck for a while.

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 (5.0-5989)

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.)

5.0-5745

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

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

Intel Xeon X5460, Nvidia GTX1060, Windows 10

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

Still don't know if other games are somewhat affected as well.
I've tried the latest Ishiiruka version 1004 and it doesn't have this problem (maybe PR 6118 hasn't been merged in it?)

I think it was possible it could be slightly slower, but, I'm surprised it something noticeable.

Maybe if you get a fifolog of an area that's slower, stenzek or tomcc can look into it and figure out why.

I hope to have catched the right moment (very difficult to get a fifo log of a stuttering moment within the 5mb limit)

P.S. the problem is not that it may be slighly slower (I haven't checked that very well, but it may have lost 1 to 2% speed), the real problem here is that the game is no more flowing: at some times (always the same times) image get "stuck" for a very brief moment (stuttering)...it's someting like the shader cache creation stuttering seen before Ubershaders 2.0, but in this case the second time you play the same scene the problem remains...
