I thought there won’t be any cross-process texture sharing on macOS anymore?

Reading the Chromium ticket, we also use globally registered Mach ports in ipc-channel, don't we? Is this something we would like to get rid of at some point?
-
Do we? It's been so long since I really dove into ipc-channel. Manish, Nika, and I have been talking about switching ipc-channel to be a layer on top of Chromium's Mojo IPC at some point, which would let us stop having to maintain that stuff.

What's the safer alternative? Just using IPC to transfer desired draw calls/layer state/whatever? (Presumably as long as you have shared memory to transfer textures it'd be OK?)

Yeah, proxy high-level graphics commands over to another trusted process, using memory-safe IPC code.
