Editor load times increased a lot with beta 15

[elenakrittik]

Godot version

Godot 4 beta 15 (UPD: the issue persists on beta 16 too)

System information

Linux 5.15.89-1 x86_64 (Manjaro XFCE)

Issue description

When opening a godot project, the window name is changed every frame-two and shows a scene name in it, which indicates that godot for some reason reopens every scene present in the current tabs, then every instanced scene (if any). First time i tried opening project (just after the system booted) it freezed and didn't load (i Ctrl-C'ed it after a minute of nothing), second time thing described above happened. Before beta 15 everything worked fine and godot loaded just the current scene in ~15 seconds, but now it takes a lot more, even though my project is not even small, it's tiny (less than 400 lines of code including website template). My best guess for this issue is #57606

Steps to reproduce

Create a new project, add a few basic scenes like Player, Level etc., keep the scene tabs open, and reopen the project.

I noticed performance issues with beta 14, 15 and 16 as well on Windows 10 22H2

This is an unrelated issue, as you can also reproduce it in betas prior to #57606 merge. There are several issues on the subject of perceived general editor slowness, such as #71795.

@elenakrittik Can you still reproduce this issue in 4.0.3-stable and 4.1-beta3?

I tested on Mageia 9 (Linux) on KDE / X11 and I can't reproduce the issue with the MRP, 4.0-beta14, beta15 and beta16 all open the project in ~6 s for me.

No, not anymore, 4.0.3 behaves as expected. Also i no longer use Manjaro, but EndeavourOS instead (linux 6.3.7-arch1-1 x86_64, Gnome/X11), maybe this affected the result.

Thanks, assuming fixed in 4.0 then.
