    Dear Theme-Fusion:

    We recently upgraded to Avada 7.1.2.

    When we perform a PageSpeed Insights test, we get the following error message:

    Does not use passive listeners to improve scrolling performance

    The above is being caused by your Smoothscroll feature (nicescroll.js file) which we are using at this time. The above affects our page loading time and also noticed the mouse wheel auto-scroll functionality does not work with Smoothscroll activated.

    When we disable Smoothscroll, mouse wheel functionality returns and the error message disappears.

    There appears to be several possible solutions to fix this issue. None are effective, however, since they affect Avada’s nicescroll.js core file. The solution (temporary) would be wiped out by Avada’s next theme update.

    This issue has existed for quite some time (prior to Avada 7.1.2). It’s time to fix it.

    Please provide a snippet or patch to fix this bug.

    Thank you!

    I second the request. It has been an issue for quite some time and needs to be addressed.

    What is the solution for this Avada bug?

    Hi,

    A couple things here:

    1. It has been stated many times, and @Jetxpert-Envato in particular, you have already been informed multiple times about this. The forum here is a community forum. It is not a support forum and it is not a way of contacting ThemeFusion. Creating a thread directly aimed towards ThemeFusion when you are already in direct communication via email is pointless and not what the forum is here for. For anybody else, if you want to report a bug which will actually be seen by our team then we have a form especially for that https://theme-fusion.com/contact-us/

    2. For this particular “bug”. It is extremely unlikely we offer any update to the script. What is a lot more likely is that we entirely remove this option and replace it with CSS options for styling the browser scrollbar. The reason why? Manipulating scroll behaviour is considered bad practice and almost always results in a poor user experience. So in terms of a proposed solution, the best option here is to simply disable the option. In terms of why we offer this in the first place then – times change and technology updates. At the time of originally offering the option browser scroll was different.

    Thanks

    @Michael_C,

    Your input is greatly appreciated!

    Respectfully, bug was presented in this forum (vs email) to ensure we can capture publicly both Theme-Fusion’s input and offer others an opportunity to provide a solution. So, please consider this post an exception to the “rule.”

    Back to the topic.

    If your proposed solution won’t cause a “FOUC” effect (pages shifting as CSS loads) and also solve the issue reported above, then by all means, please offer it. Until then, please don’t remove the smooth scrolling feature from Avada. Many use it and it loads much better than the smooth scrolling effect(s) offered by many plugins.

    By the way, this forum has been very helpful to us. We certainly hope it has also been useful to Theme-Fusion to understand the impact your theme and revisions have on the community. If we don’t post these type of topics in this forum, then where should we post them?

    Again, thank you!

    Hi @Jetxpert-Envato

    Your thread starts with – Dear Theme-Fusion. There is no room for misinterpretation there. You already talked to Ammar and raised this point, then went ahead and create a forum thread addressing the company directly. If you truly wanted user help on the issue you would not go about it that way.

    You can continue to use the forum for its intended purpose – which is user to user interaction. Using the forum as a mechanism to leverage a company response on something you already brought up (and did receive feedback on) is separate and will not be tolerated. I believe that to be clear and straight to the point.

    Thanks

    @Michael_C,

    Apologies for the inconvenience. We’ll use “Dear Community” next time.

    Our records indicate we did not talk to Ammar about this specific issue.

    If you believe we did, please drop me a note showing what we sent him.

    Cheers!
