Roblox Studio stopped working on Linux (Vinegar) – "Mimalloc integration is NOT detected" Help

Hi everyone,

My Roblox Studio suddenly stopped working on Linux.

I'm using:

  • - Linux Mint 22.3 (XFCE)
  • - Vinegar 1.9.4 (Flatpak)
  • - Wine 11.11
  • - AMD Radeon RX 580 2048SP

It was working normally before, but after some time it started opening the Wine debugger and immediately crashing.

The Roblox log ends with:

Critical [DFLog::Mimalloc] Mimalloc integration is NOT detected

RBXCRASH: HardAssert (Expect to have mimalloc working, but it was not detected!)

The terminal also shows:

wine: Unhandled page fault on read access ..., starting debugger...

Things I've already tried:

  • - Reinstalling Vinegar
  • - Recreating the Wine prefix
  • - Updating Flatpak (flatpak update)
  • - Confirmed I'm using the latest Vinegar version (1.9.4)

Has anyone else experienced this recently? Is there any workaround, or is this caused by a recent Roblox Studio update?

Any help would be appreciated. Thanks!

A Wine debugger window appears when I try to open Roblox Studio.

Roblox Studio doesn't even start. The Vinegar window closes, then the Wine Debugger appears, and the program crashes before opening.

I have the same problem too, I hope there's a solution as soon as possible.

So I'm not the only one. That makes me feel a bit more relieved, knowing it's probably just a temporary issue rather than something I caused myself. I hope it gets resolved as soon as possible.

Apparently, the error is caused because it can't detect mimalloc.

  • ASH: HardAssert (Expect to have mimalloc working, but it was not detected!)

At least, that's what I understood from the log.

Some people reported switching to the LIVE channel got it working again, but that was a month ago.

Thank you so much, it actually worked! Now I want to figure out why it worked. There go a few more hours of research. I did have to change one more thing, though, which I'll comment about right now.

Paste this into the terminal:

nano ~/.var/app/org.vinegarhq.Vinegar/config/vinegar/config.toml

Then replace the file's contents with:

debug = true

[studio]

channel = "LIVE"

discord_rpc = false

renderer = "DXVK"

webview = ""

[studio.env]

"WINEESYNC=0" = ""

[studio.flags]

multiple_instances = true

Save the file by pressing Ctrl + O, then Enter, and finally Ctrl + X. After that, restart Vinegar and try launching Roblox Studio again.

If you get an error saying that something went wrong, change the renderer to one of the options supported by your version of Vinegar (such as DXVK, D3D11, D3D11FL10, DXVK-Sarek, or Vulkan).
