Description

Game Name?

Sonic Riders Zero Gravity

Game ID? (right click the game in the game list, Properties, Info tab)

RS9E8P

What's the problem? Describe what went wrong.

In a four player game, the bottom right screen will flicker black constantly.

What steps will reproduce the problem?

Start a 4 player free race and pick a stage. The first stage will work, but I believe they all do this. It should show up as soon as all 4 screens appear.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

It is present in 5.0-12346

Is the issue present in the latest stable version?

Not in 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.)

This first broke in 5.0-5366. It works in 5.0-5362.

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

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

In version 5.0-3366, if you uncheck "store EFB copies to texture only", the bottom right screen looks mostly correct. On 5.0-12346, doing this makes the third player screen flicker on the fourth player screen, rather than just flickering black.

I have a hunch that maybe this is some kind of weird texture memory issue and is somewhat unrelated to the actual regression start based on some of the behavior I observed.

For my sanity in the future, direct link to the bisect build -> https://dolphin-emu.org/download/dev/425a8cb378fca29fcdc8ef52673763a5492fa43b/

I am correct.

Phire's tmem branch fixes the issue in EFB2RAM (and is known to not be 100% done for EFB2Tex)

Actually doesn't. It was a cleanup shortly after the original tmem.

This is a duplicate.

This is the same as #12661

I've attached fifologs with EFB to texture on and off.
Issue still occurs as described on 5.0-17197.

As much as I hate to admit it, this probably isn't worth being a current issue.

It's an annoying regression, but it only shows up in 4 player and you can mostly avoid it by using EFB2RAM.
