Dota 2 crashes on some macOS devices when GPU capture is enabled #2146

Without GPU capture, everything seems fine.

I'll continue to look into it. I don't have any symbols, so this might be difficult to investigate.

Seems to happen with MoltenVK as well. So it could be either a bug with Dota 2 or a misbehaving driver/somewhere within macOS internals.

Here's another screenshot that appears to capture the same issue:

From glancing at the screenshot it seems to imply Dota 2 causes the issue, but it's hard to tell.
