What happened?

This happened after I upgraded my OS from Linux Mint 20.3 to 21 (Ubuntu 20.04 -> 22.04). However it also happened after a smaller system update on Fedora 36.

The dev tools no longer work unless Pulsar is launched with --no-sandbox. The application itself launches normally but any attempts to open the tools fail (Window: Toggle Dev Tools, ctrl+shift+i, view > developer > toggle developer tools). No errors created, no logging to the terminal.

Launching with --no-sandbox causes them to work again (resolution from @DeeDeeG).

Ideally Pulsar should be able to open the dev tools regardless of whether --in-process-gpu or --no-sandbox is used. It should certainly throw an error if it is unable to open the dev tools for whatever reason.

Which OS does this happen on?

🐧 Debian based (Linux Mint, Ubuntu, etc.)

OS details

Linux Mint 21 (but also on Fedora 36)

Which CPU architecture are you running this on?

64-bit(x86_64)

What steps are needed to reproduce this?

1. Launch Pulsar with no additional parameters from dev, appimage or tar.gz binary.
2. Attempt to open dev tools

Context: The part where these flags are needed at all is a known issue, happening on any recent Linux distro and Electron versions less than 13.x latest.

Best solutions would be:

• Get on Electron 13+
• Or as a workaround, do one of the the --in-process-gpu or --no-sandbox flags.

Due to your pointing it out and folks testing both flags to compare, what's new since that original issue was posted, is that we now know --in-process-gpu breaks the Dev Tools.
