Low scrolling performance in Safari

[NikSimonov]

I have issues with scrolling performance in Safari, using latest version without jquery. Can you give me any optimization advice?

[KingSora]

Yes, please answer me some questions first:

• On which element are you using the plugin and with which options are you initializing it?
• Which OS version and which Safari version are you using?
• If you are using a different browser, is the performance the same as in Safari?
• On how many elements are you initializing the plugin?
• Can you perhaps provide the link to your page so I can check what might cause the issue?
• Is the scroll-performance on the documentation page also "low"?

[NikSimonov]

• using it on body, options are { autoUpdate: true, sizeAutoCapable: false }
• OS 10.13.5, Safari 11.1.1
• works perfectly fine in Chrome and Firefox
• just the body
• sorry, but i can't, maybe I'll look into any specific elements, that can cause problems?
• performance is fine on the documentation page

Okay, nevermind, figured it out. Page has many placeholder images with filter: brightness(0) contrast(0);

Is there any particular reason why you've set the autoUpdate to true?
Please initialize the plugin with autoUpdate : null (thats the default value). This should increase the performance.

It was your question "Does the option autoUpdate : true improve the performance?"
I thought, if you asked about it, so there is a way it can improve it, that's it.
Reverting to default. Thanks for helping out.

Now I understand.
Genereally autoUpdate : null will give you the best performance for your browser. Only in some very special cases (like many animations or very many elements) you want to
use a updade-loop with autoUpdate : true because the updates will happen on a frequent basis. - But even in this cases a performance gain isn't very likely, but nevertheless I wanted to mention this possibility in the previous issue.

I'm glad I could help you, if you have other questions or problems, please don't hesitate to open a issue!
