NSWindowShouldDragOnGesture on macOS is not working with Signal

[marcolaux]

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

With the setting NSWindowShouldDragOnGesture enabled the user is able to drag any window at any cursor position via CTRL+ALT+Mouse1.

This doesn't seem to work with current Signal versions.

Steps to reproduce

1. defaults write -g NSWindowShouldDragOnGesture -bool true
2. restart
3. See that you can drag any window with CTRL+ALT+Mouse1 at any cursor position
4. See that this doesn't work with Signal

Expected result

it works like other macOS windows

Actual result

the mouse click just gets registered as a normal mouse click

@marcolaux appears to be an issue with Electron. Did this work in previous Signal versions?

It looks like it - thanks for the hint.

It indeed worked in previous versions and I only noticed it recently. I use the gesture regularly.

Other apps have the same issue with newer Electron versions I have been told.

You seem to have most context on the issue, could you report it upstream, please? Thank you!
