Mapbox responds slowly in Devexpress’s XTRAMap - winforms

When I show a map using MapBox, it takes 20-30 seconds for the map to fill in the map panels. If I change the source to Bing, it comes in instantly. This is a recent development. Has anyone seen this problem?

React-Three-Fiber's Canvas freaks out on Android phone

I'm creating my first web app using React and I've implemented some 3D animations using React-Three-Fiber.
I've already deployed the page in github pages and while in Chrome on the desktop, both in the webpage and in localhost the website works flawlessly (has some freezes but that's not the point).
However, when I visit the page on an Android Phone, all the Canvas stop working and display the text multiple times whenever I scroll (I don't really know how to explain what's happening, so I'll leave this video: https://youtube.com/shorts/O0xXEElAjJs?feature=share . You can see that the problem only exists on the Canvas, since the Header is not a Canvas element).
I've tried to load the page on iPhones but it doesn't even load and just crashes.
On two of the Android phones I've tried, the page loaded nicely at start but after some time it started glitching like in the video.
I have absolutely no clue on what is going on, other than the problem lies on the Canvas that I have created.
I assume this is a simple thing that I might have missed but I'm really lost.
Thanks in advance! :D

How to load images faster and improve performance of website (React JS, GSAP and Netlify)?

I have a website which is deployed on Netlify below:
https://hungry-mclean-362570.netlify.com/
Github:
https://github.com/shindosu/mutsuki-portfolio-client
To give a bit of a background, the app is powered with React JS. In the Home page within the <div id="right-side">, I have two React components being rendered. They each are powered by THREE JS, and it is alternating between two pictures infinitely with image transition animations via GSAP. So in total, I have 4 images being rendered on the right hand side. The size of the images are around 13MB total (more images to come)
I also have a slider, where if the value hits >=50 then the styling and the images will change to let the user know the "category" of the images that they are looking at.
Now, it is no where near being done so don't mind the incompleteness. What's bothering me is the loading time of the images (handled by THREE JS, GSAP) is taking an insanely long time to load, which I think is also affecting the loading time of the other elements as well.
How am I able to speed up the loading process?
I tried decreasing the image sizes (it was 60MB before..currently 13MB!); am trying to shred off more but the most I can get down to is around 600~KB/img without losing any substantial quality.
Are there any other way to get around this? This will be a portfolio website so there's more images that will be in the projects page, so I'm assuming if I continue the way that I'm doing right now the outcome is going to be as or more worse than the page that I am working on.
Thank you for your time!
To load images faster in a React application you can use one of the following techniques:
Use lazy loading method --> The image loads only when the user scrolls to it.
Use blur technique --> This loads the images in low resolution initially before the original load
Use JPEG-XR and WebP instead of PNG, JPG etc.
For more details you can refer to https://teacode.io/blog/how-to-speed-up-your-react-app-using-cloudinary-and-lazy-loading
Note: I am not an expert. I was also searching how to increase load speed of images and came across some articles like that mentioned above.

Angular JS application taking around 100% CPU while resizing

My website is in AngularJS v1.7.2 (using Laravel PHP framework as backend).
Current issue is the website freezes after resizing several times (2-3 or more times). I have checked Google chrome Task Manager Tool and it showing around 100% of CPU usage at the time of freezes. Same issue also occurred while testing the site in mobile by changing orientation several times. I have already tried solution like bind one way, add track by for ng-repeat, using tools like Batarang but no luck yet. Is there any proper solution for the issue. Please let me know.
UPDATE
The website almost finish. Only the freeze issue currently blocking us. The website mainly containing song, album, playlist, artist.
On home page there is banner (4 images) using iosSlider . then there are per category (8 categories) album (5 album each). on right sidebar there are song list. There are other pages like category page, artist page, album page, song page, user profile pages etc. Also there is a customised player using angular soundmanager2 API. Generally while viewing in desktop normally there no issue so far. But if I check using Device Toolbar (CTRL+Shift+M) and switch to other pages and rotate 2-3 times it just freezes. Even can't reload or refresh the page tab. If I check Chrome Task manager (Shift+Esc) it shows around 100% CPU usages
that time. Thing to notice the issue only occurring if I route to other page(forward or backward or both) then rotate 2-3 times. I am using AngularJS Batarang to sort out the issue but with no clue still now
SOLVED
The issue was with iosSlider. After removing the iosSlider no crash issue now.

screen (html page) juddering vigorously while scrolling up or down due to pull to refresh hook on phonegap (onsen ui)

I finally finished my phonegap app. I put the config.xml file and all my html, css and js files in a folder and uploaded it to phonegap build. I downloaded the ipa file to test it on my iphone.
The app has a page where articles are loaded from a json page that I am hosting on a server. The articles load properly. However when I hold the screen and scroll up or down, the screen starts shaking vigorously. I looked at other forums to see but all I found is DisallowOverscroll. But DisallowOverscroll set to true makes sure that the screen doesn't bounce if scrolled entirely to the bottom or to the top. But my problem is once I put my finger on the screen and scroll down, the page starts shaking up and down. I tried everything for the past two days but nothing worked. Any help is really appreciated.
I also made a video to make it easier. https://www.youtube.com/watch?v=O-Nd4ntZ46E
EDIT: I figured that the problem is arising from pull hook feature (pull to refresh. When I tested the page without the pull to refresh hook, it is working absolutely fine. But I am not sure how to use pull to refresh hook and not make the page judder at the same time.
Theres a mistake on your resolution for iPhone 6, it should be 750 x 1334, also check the image file is the correct size too.
You'll need to show code for the other problem.
