🐞 System becomes extremely slow if loop is used too much

[anthunyy]

Bug Description

When Loop is used too much, i.e. moving a screen left and right, over time, programs are slow to use, and at some point, nothing is usable. All problems end if Loop is quit, but this may be difficult if your system is running very slow. Major problem.

Steps To Reproduce

1. Create hundreds of loops (or have a Python script press fn + whatever)
2. Watch your system slow down
3. Quit loop
4. Everything is fine
5. Repeat

Reproducing using Python script (uses pyautogui):

import pyautogui
import time

def right():
    pyautogui.keyDown('fn')
    pyautogui.press('right')
    pyautogui.keyUp('fn')


def left():
    pyautogui.keyDown('fn')
    pyautogui.press('left')
    pyautogui.keyUp('fn')

#I would recommend adding a way to quit easily, not required
while True:
    right()
    left()

Expected Behavior

Loop is expected to not slow down your system a ton if used too much

Actual Behavior

Loop slows down your system a lot if used too much. Mostly noticed because no one is doing hundreds of loops

This is a duplicate of #626 although you've added some py script, but, even after not closing loop for a week and using it over 700 times, I still have not felt the system be sluggish nor slow, i guess we'll have to look into it more.

Can confirm the behavior.

Can't figure out what exactly reproduce the issue. I first re-used Loop today, since a long time ago.
Quitting Loop does fix instantly the issue.
When it happens, All mouse event will be then delayed.

I only use my Macbook w/ Trackpad and no external screen right now.

On top of my head, app that I use that could maybe interfere with the bug triggering would be Swish and / or BetterTouchTool.

Same problem. Trackpad becomes unusable laggy when using loop for 2-3 days. A loop restart fixes the issue for another 2-3 days.
