Flexslider is not working fine in my sites, they always flicker on load.

I used all CSS hacks.
Feel free to suggest other sliders, I am open to try new
Just want smooth sliding of images

I am using the Flickity slider (from Metafizzy) in a landing page to show different products. The slider is in portrait size and not landscape.
The issue is that when the user only scrolls the top portion of the slider into the viewport on mobile (i.e. 20-30%) and they attempt to scroll/swipe the slide, the screen suddenly jumps to attempt to include the whole slider into the viewport.
This never happens on the mobile emulator on the desktop, but only on the smartphone device on safari and google chrome browsers
Is this intended to be a specific behaviour for the Flickity slider? Like I should not be using it to make portrait sliders? I've gone through the plugin options and not able to fix this behaviour. It never came up in early testing with dummy content.
I've provided a link to the github page where it is happening, you can open it up in mobile browser and see the viewport "jumping" bug when you attempt to scroll the table. https://true-digital-channel.github.io/Galaxy11-Preorder/build/mobile.html
Disable the keyboard accessibility by setting accessibility: false in the carousel options. From the Flickity issue tracker.
Sometimes in my UWP app I experience a problem while scrolling with my scrollwheel. Basically the scrollbar moves when I use my scrollwheel, but the content isn't rendered properly; resulting in an empty block which gets scrolled up and down.
Yet everything works fine when I click and hold the scrollbar instead of using the scrollwheel on my mouse.
I have to restart my UWP app in order to get things back to normal.
The issue appears while scrolling a default XAML ListView, but also in a RadDataGrid (Telerik).
I have made a screen recordingo of this issue, which hopefully will illustrate what's happening more clearly.

I haven't found exact steps to reproduce this issue, it just seems to be there at random from time to time.
Does anybody have an idea what might be going on here and how this could be fixed?
I'm using PhantomJS to take screenshots of a lot of web pages. Some of these web pages have short animated gifs on them. No matter how long of a timeout I use between loading a page and using page.render, I still just get the first frame of the gif. Is there anyway to make phantomJS run the gif animation?
I'm having some issues with a website that only occur in Safari. I'm running version 5.1.7 (7534.57.2) on a Mac.
You can view the site here: http://mcad.edu/annual-report-2011-12/.
The website is parallax scrolling, with a relative positioned content div that holds everything, including the 3 parallax scrolling backgrounds which are all fixed, top and left set to 0.
Within the fixed parallax background containers, colorized images fade into full color images when a user mouses over them. For each "image", there are two divs stacked, each with background images that are positioned by background-position. The div on the bottom has the colorized image. The div on top has the full color image as a background and has its opacity set to 0 until mouseover. The fade is achieved using a CSS transition on the opacity property so that the top div becomes visible.
So, in Safari only, when I mouse over any of these divs, the transition occurs smoothly but all of the content in the same parallax scrolling background div shifts/jumps in the process. If I remove the CSS transition, this does not occur.
I think that it might have something to do with the transition/webkit-transition property not playing nicely with a fixed position container in Safari. However, all of the issues I've found that relate to that are from 2010 and mention a Safari bug that I assume has been fixed…two years later. But maybe not.
There's also another issue with the Catalyst section (3rd dot down on the right navigation). These animated images work as links in Chrome, Firefox and Opera, but not Safari. Any ideas?
I have a similar issue with a fixed position and transition-duration for a header menu I've created. When a visitor scrolls down, the menu has a box shadow that fades into place. Well when this is viewed on safari in a MacOS, I get a weird sliding in issue. To easily fix this, after spending way to much time searching for answers, I'm removing the transition effect for macs. This fixes the slide in issue but gets rid of the transition effect sadly.
So as you were speculating, it probably is the transition duration on your project as well. The best thing for this would probably be to make a Mac-Safari CSS file, get rid of the transition-duration for that particular area and move on with your project.
Best I can suggest for now. Hope it helps.
I need to show a paginated slideshow of moderately DOM-intensive HTML pages in an iPad application.
All documents are tailored for iPad screen so there is never any scrolling inside UIWebViews.
I decided to put UIWebViews inside UIScrollView for pagination.
It works really well and smooth after all web views have rendered their content.
However, I can't afford waiting for 20, 30 or 50 web views to load before user can scroll: it takes minutes.
I tried to anticipate swipes in scrollViewDidScroll handler and pre-load a few next pages as user keep scrolling.
This worked much better (no performance difference between 10 or 150 web views).
However calling loadHTMLString in scrollViewDidScroll handler causes scrolling to lose it smoothness.
I don't care if it takes a second longer to show a particular UIWebView—all I want is for scrolling to be smooth and available as soon as possible, and to lazily preload UIWebViews on the go.
How do I achieve that?
This is a difficult problem and there is no easy/elegant way to solve it.
One way to speed up the scroll would be to lazy load the pages as you stated in your question. However, in order to ensure smoothness you would have to control when the loading happens.
So say you began by loading the first 5 pages on initial launch. When the user scrolls to page 2 and STOPS, you begin loading page 6. As soon as the user starts scrolling again you pause the loading only to resume when they have stopped on a new page. Pausing the loading in between will help smooth out the scrolling. Also, make sure you release data when possible because it can build up and hinder smooth scrolling down the line.
Another option would be to have the UIWebViews begin loading only as soon as the user stops on the page. So say I scroll to page to, once the scrolling stops I begin to load the HTML. This is not as "pretty" as the first options but it will ensure that the scrolling is smooth.
Another option, this one is a bit out there, is to run through and load all the HTML pages rich text. Leaving out all the DOM intensive stuff. Then grab a screen shot of those semi-loaded page using this method. When the user stops on the page you load it all the way including the DOM intensive stuff. This will let the user feel as thought they are scrolling quick with everything loaded.
Here is a great scrolling class that I have used before.
Here is some code to help with method 3.
Good luck and I hope that this helps!
EDIT:
Here is a great post from the guys at LinkedIn on how they solved webView scrolling problems. It would be worth a read.
