In the latest Google Chrome Version 108.0.5359.95 (Official Build) (64-bit) with default settings, I observe that making new tab
always starts new process (even if I open same site as in another tab).
But if an existing tab is duplicated:
then both new and old tabs share the same process. It can be observed both in operating system and Chrome Task Manager (opened by Shift+Esc):
The latter scenario – two tabs in one process – produces some weird errors for my site, which uses WASM multi-threading and 3D rendering. For example after duplication, the original tab finishes with an error in an WebGL shader, which never happens if the tab owns uniquely a process.
Is there a way to make Chrome duplicate a tab with my site by always creating a new process?
