【現象】
Safariブラウザでcanvasに対して任意の描画をした後、clearRect()を実行します。
その後、canvasの親divに対して visibility: hidden を設定すると、消したはずの描画が復活します。
但し、親divは正常に visibility: hidden が働いているので描画されなくなります。
また、この現象はブラウザの拡大率が影響をしているようです。
少なくとも後述のリスト内のMacbookAirでは、拡大率が100%の場合にのみ発生しています。
この現象は過去のバージョンでは起きてないようです。
このバグを修正する予定はありますか？

If I set an input text box connected to a datalist-options, in order to suggest pre-coded values, this is what happens:
The text field shows properly.
When I start typing, one or more coincident "options" from the datalist are shown at the bottom of the available screen.
When one option is selected, the data contained in it is NOT transcript to the input field.
The same webtest works fine on Ipad mini w/ios 15.
Try this simple code, it doesn't work:
<label for="browser">Choose your browser from the list:</label>
<input list="browsers" name="browser" id="browser">
<datalist id="browsers">
<option value="Edge">
<option value="Firefox">
<option value="Chrome">

I'm not sure if I just missed a recent breaking change, but we are having an issue with the camera in our single page app on iOS 17.4.1 in Safari. We can open the camera and display it to the user using getUserMedia. However, if the path of the site changes at all (for example, the user clicks a button to opens a sidepanel which results in the path in the browser changing) the camera goes black, even if the video element is still being displayed.
I can see in the browser that the camera has stopped, and the user has to re-enable it manually by tapping "Start Using Camera".
Any idea's what could be going on here?

I am developing a web application that works on webview.
From iOS 13, users could set a specific language for each individual app, and every webview-based application knew the application language through navigator.language.
However, in iOS 17.4, this API returns the system language instead of the individual app's language in web applications.
Is this an official change in iOS 17.4 or a bug?

Even when iOS's '"." Shortcut' keyboard setting is enabled, double-tapping the spacebar in WKWebView doesn't insert a period.
While making WKWebView editable , "." shortcut is not working. It works fine when any other external keyboard is used. I am facing this issue in WKWebView using apple keyboard. Even forceful adding javascript to replace double tap of space bar to period character logic is not working.

Hello,
I've encountered an issue with the scrollbar functionality on my webpage specifically when accessed through Safari. Despite its functionality on other browsers and devices, Safari on iOS 14 displays only the native scrollbar during scrolling, contrary to the desired behaviour of consistently showing the scrollbar.
&::-webkit-scrollbar {
height: 2px;
}
&::-webkit-scrollbar-track {
background-color: "white";
margin-left: 4px;

Hello community, first post I hope to meet the guidelines.
I am developing a web site that uses a library that involves audio playback.
This playback is accompanied by an animated canva, and in the IOS17 version in safari, this does not work. The audio is muted and the canva does not animate.
However, in ios16 safari it works perfectly.
I have also tried in safari on MacOs and ipadOs and it works, which makes me see that the problem is with ios 17 safari.
The library in question is this: https://github.com/foobar404/Wave.js/
I don't think the failure is in the library since it works as I said in all other platforms.
Specifically the code is here: https://github.com/foobar404/wave.js/blob/main/src/index.ts and makes me think that some HTML element is being incompatible.
It is necessary to emphasize that in ios17 it does not work, but it does not appear any error in console.
I would love to get help or know if this is a bug to report it.

Hi,
After iOS 17 software update, we've encountered an anomaly with the video element within our videojs player. Upon video load, there's a noticeable shift and recentring of the video to its correct position.
This issue becomes more pronounced when the player is in a horizontal orientation while the video being played is vertical.
Additionally, we've observed resizing and cropping issues during the initialization of the player, which were not present in earlier versions. In our current implementation, we have a canvas element inserted before the player. Due to resizing, the video sticks to the canvas and fails to return to the correct position.
<div>
<video class="vjs-tech"
webkit-playsinline
playsinline
src="hls video source">
</video>
<canvas style="filter: blur(15px)" class="vjs-tech custom-canvas" width="412" height="320">

Hello,
I am looking for help with displaying Smart Banners on mobile devices. What is the preferred coding that can have Smart Banners appear on all devices? I am having an issue where an Smart Banner is not properly functioning as I would like it to. I would like the CTA (Call-To-Action) to be positioned on the top of a mobile screen. If a user has the mobile app already, it should read OPEN and opens into the app when it is clicked. If the user does not have the app, it should read GET and take a user to the mobile app store when it is clicked.

Hello, I am experiencing an issue when running a script on Safari, specifically WebKit. Here is a sample HTML code:
<!DOCTYPE html>
<html lang="en">
<head>
<script>
function delayedFocus(e) {
e.preventDefault();
setTimeout(function() {
e.target.focus();
}, 1000); // Adjust the delay time as needed (in milliseconds)
}
</script>
</head>
<body>
<ul>
<li>
<input type="text" id="testtext" onmousedown="delayedFocus(event)">
</li>
</ul>
</body>
</html>
The logic behind this script is to introduce a 1-second delay when the user clicks on the textbox. After 1 second, the keyboard should appear.
Testing on Android mobile devices shows the expected behavior. However, on iPhones, the textbox receives focus, but the keyboard does not appear. This issue has been observed on various iOS versions, with the script working only on iOS 15.
If you have any insights or solutions to address this compatibility issue, it would be greatly appreciated. Thank you.

I have a table with a filter. The table only displays the table rows that matches the filter. In the javascript code, I have a filterInteraction() function that have a commonElements list and display the table rows if they are included in the commonElements list. In my html, when the user click, the filterInteraction() will be triggered. Here's part of my filterInteraction() function (the sensitive code is removed): "
function filterInteraction(){
let searchList = searchResult();
let checkboxList = checkboxResult();
let commonElements = searchList.filter(element => checkboxList.includes(element));
console.log("commonElements ==========", commonElements)
var table, tr, i;
table = document.getElementById("employeeTable");
let rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
let currentName = rows[i].getElementsByTagName("td")[0].textContent.trim();
if(commonElements.includes(currentName)){
rows[i].style.visibility = "visible";
// rows[i].removeAttribute("hidden");
// rows[i].style.display = "";
}
else{
rows[i].style.visibility = "hidden";
// rows[i].setAttribute("hidden", true);
// rows[i].style.display = "none";
}
}
countPart(commonElements.length);
}".
In this function, I printed the commonElements list, and the list is always correct. However, for the display, it's switching between displaying nothing and displaying the correct rows. (When entering the Safari, the first click on the filter makes the table empty, but the second click displays the correct rows, the next click will make the table displays nothing again .... ). Even during the time that the table display nothing, the commonElements list printed in console is still correct, which means the function does have the correct table rows, but they are not displayed. I tried three different ways to display the table row: "rows[i].style.visibility = "visible"; rows[i].removeAttribute("hidden"); rows[i].style.display = "";". None of them could work without the bug I mentioned above. I tested my filter on Chrome, FireFox, and IE, and my filter works perfectly on them. Any possible way to solve the issue on Safari? Why it has the display bug like this in Safari? Really need help!!! Thanks

Hi,
We are facing an issue in our page , The same works fine in other operating systems like android and windows.
we are facing this issue only on IOS and MAC(safari browser alone ).
We have a loader with us ,which will be shown in 2 different phases in our page. The first time loader will be shown while page is being loaded, the second loader will be shown once the user clicks on pay button.
the first loader is not giving any issues for us .But the second loader is not loading completely as you can see in the attached not working image ,the blue circle is being displayed only a 5-10%. It should start from 0 and gradually should reach 100% and again a loop.
From the analysis we could see the loader rotates fine after clicking pay button ,but once after page is submitted the issue happens
document.paypage.submit(); (code attached below) // this is the form submission in our page // once the control reaches this line we could see the loader is not working fine.
the same scenario is checked in android ,but even after page submission the loader works fine, Only in IOS and mac we are facing issue in (safari in mac other browser works fine without any issue), (all browsers in iOS).
please direct us to solve the issue
