Object Effects increase intensity every time an object with effects is deleted and created

[VegeTato]

Describe the bug

if you create an infinite falling objects event, AND if you create another event to remove the objects when its out of screen, OR by just adding the behavior (remove when out of screen), the effect settings (numbers) will start to increase every time the object spawn in endless time, and this applies to all effects.
in my example i used glow effect, but the bug happens in every effect as well.

Steps to reproduce the behavior:

1. Go to object behavior
2. Click on Effects
3. Pick any effect you want
4. Set the behavior (delete when out of screen)
5. Got events
6. Create an action: create object every frame, X:random in range(0,screen width) Y:0
7. Preview the scene and you should see every spawned object effects getting increased in every frame

• GDevelop 5.0.0-beta 117 / Desktop
• an example of how this bug may face the user: if the user made a simple bullet shoot game and added "delete when off screen" behavior to the bullets, and then he wanted to add effects for the bullets, the bug will happen.

Do you have an idea? @HarsimranVirk

I can reproduce (thanks a lot for the project!) and this is definitely weird. I'll try to take a deeper look.

Bringing over details from #3126 as it is related to the same item.

Describe the bug

When creating a sprite that has an effect (tested with Brightness or Adjustment) and then destroying it many times in a row.
After a few repeats the last created sprites effect that should be set as a value between 0 to 1 is not working properly.

To Reproduce

The example creates an object and then changes the brightness value that is the angle from the object to mouse cursor divided by 360 and added with 0.5 to make the value in the range 0 to 1.

the first iteration works as intended, then create and destroy the object a few dozen times and then the last object will go from 0 to 1 in only 45 or so degrees instead of the full 360 degrees.

The brightness effect setting returns to normalish when you create many more objects in a row and delete them all at once.

I have recreated this issue and tried discussing it in discord and seems that it's not working properly.

Attached is the example project and a video showing the problem.
