What's the problem? Describe what went wrong.
After some time, anything with a overlay during play, like scan visor, flickers. And everything with an overlay that pauses the game, like saving corrupts the background image. Then it returns to normal when the overlays disappear.
What steps will reproduce the problem?
- Play the game for a while. Seems to happen sooner if you travel using Samus' ship.
- Save or open up scan visor.
- you should see flickering for scan and corruption for save.
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. 5.0-8116
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.)
Can't because the program provided an error.
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
Could not provide the diff file. Everytime I tried, it ended with the program locking me out because I could not interact with the pop up. It said it expected 95 but got a higher number.
What are your PC specifications? (CPU, GPU, Operating System, more)
CPU: Ryzen 5 1600
GPU: AMD's 480 (red devil)
OS: Windows 10
RAM:: 16 GB
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
There should be a screen shot of the save corruption.

I was experiencing this the other day, but now I can't reproduce it. Seems to depend on the phase of the moon or something...

Okay, so this is a dual core timing issue. Using single core fixes it, but also the texture loading speedup of PR #7170 (which fixes some stutters in this game) seems to also make the issue magically go away.

Ah.
I tend to get it consistently when the cutscene where you travel to Phazze plays.

Um, the dual core thing did not work. Cutscene and scan still flickered.

I can confirm this still happen, and in Metroid Prime and Echos on Trilogy as well. But I can provide some new and useful information!
You can work around it somewhat by turning on Immediately Present XFB, but when you do, the old "black bar" behavior returns. This leads me to believe it's related to dual core thread synchronization. Which means it'd probably be almost impossible to fix without performance hits comparable to the existing options to synchronize things more tightly?
Still, if the performance hit from those is too great for you, Immediately Present XFB at least lets you get to a save station without getting a headache from the flickering so you can re-sync the threads by restarting the game. If it's a rare occurrence for you, that might be enough.
