Description

I understand that there should be no bug reports regarding pre-Mojave, however, when using panic alerts for the Unsupported Metal warning, not one game will launch.
Before 5.0-10451, games were able to launch. Now, games would not even load.
Instead of using panic alerts, I would instead use an OSD Notification displayed for 60 seconds.
With OSD, the game will now launch.
I have created a pull request that uses the OSD fix, and will be uploaded soon

Game Name?

ANY

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

ANY

MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)

ANY

What's the problem? Describe what went wrong.

Pre-Mojave will display Panic Alert with Warning that Metal is unsupported, clicking either button will not render the game.

What steps will reproduce the problem?

  1. Use Vulcan Backend
  2. Run game
  3. Click either option.

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, 5.0-4097

Is the issue present in the latest stable version?

N/A

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.)

5.0-10451

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

History

#1 Updated by Techjar 10 months ago

This panic alert doesn't check the result at all, so I don't see how it could be causing a crash. There must be some shenanigans going on here. Try some obvious things like disabling dual core. If an unchecked panic alert is causing crashes we'd like to figure out why.

#2 Updated by Techjar 10 months ago

Additionally, I'm not able to reproduce this behavior by modifying the code to display the panic alert regardless. That's on Linux though, so it could be a weird mac-OS-specific Qt issue.

#3 Updated by jpapetti0713 10 months ago

Disabling Duel Core, Panic Handlers and Changing the emulation engine does not help.

I will post a screencap in the next post.

#5 Updated by Techjar 10 months ago

I still can't reason why that would be happening. Maybe it's a weird interaction with Apple's Intel Iris graphics driver, as VinDuv cannot reproduce it on NVIDIA.
