WebUI freeze

[Timmy-the-nobody]

Prerequisites

• I'm sure both client and server are on the latest update.
• I have read the console error message carefully (if applicable).

Your Environment

• Version: 1.64.8
• Operating System: Windows 11

Description

When sending too much events from JS to lua the whole WebUI page freezes and become unusable

Steps to reproduce the behavior

Install this package on your server:
webui-bug-package.zip

It contains a web page, which runs this every 5ms

setInterval(() => {
    Events.Call("SomeEvent");
    Events.Call("SomeEvent");
    Events.Call("SomeEvent");
    Events.Call("SomeEvent");
    Events.Call("SomeEvent");
    Events.Call("SomeEvent");
}, 5);

In the page there's a button that changes color when hovered
After a bit of time, hovering the button will not change it's color

Expected behavior

The page shouldn't freeze

Actual behavior

The page freeze, and the only way to unfreeze it is by reloading the package and recreate the WebUI instance

well I think it's quite expected when sending > 1000 events per second

There should be a mitigation for that imo

@Timmy-the-nobody does it still happen for you?
How much time did you wait for the button to start getting unresponsive?

[gtnardy]

nvm after a few minutes it started lagging for me

[gtnardy]

nvm again, I think I only had the lagging because I had verbose logs enabled, and it was generating thousands of logs per second

I havn't tried again, but when it happened it was almost instant with the snippet i sent

[gtnardy]

@Timmy-the-nobody could you try again please (the snippet still works perfectly 😄)? (with logs verbose disabled then enabled) just so we can make sure?

Will try next time I launch the game

[Timmy-the-nobody]

@gtnardy i tried again and it didn't crash at all, with and without verbose logs.
Before the freeze was instantaneous, I added a 50ms min mitigation between 2 events sent to make sure it'd never happen, but I guess I can remove it now

That's great to know, I will close the issue then! Probably it was fixed in some of my CEF improvements/bug fixes
