Cannot help without a proper demo.

[github-actions]

An isolated working demo is required in order to analyze this issue.
You can easily create a demo on Codepen/JSFiddle/CodeSandBox by clicking the buttons on the top of every example in the documentation.

Why this is important:

• I do not have the time to reproduce every test case from scratch
• your bug might be related to your own application and not Photo Sphere Viewer (thus I will be unable to reproduce it)
• taking the time to create a demo yourself allows to take a step back and find the solution yourself

DO'S and DON'TS:

• DON'T use minified source files in your demo
• DON'T share your code inside a ZIP, I will only look at online demos
• DO isolate the viewer from the rest of the app, if possible
• DO describe the step-by-step workflow to reproduce the issue

Hi,
Hope you're having a great day.

I’ve created the demo and sent you the link.
I’ve also attached a video to show you the issue.

As you can see, the tiles occasionally encounter problems.
I’ve checked everything, and the issue is not related to the internet connection as the images download without any problems. The issue is with the library.
(In image 5, for example, the images didn’t display correctly, but after switching between image 4 and image 5 once, the issue was resolved.)

At the end of the video, to ensure the problem isn’t network-related and that the images are indeed downloaded, I opened the undownloaded images to check if they could fix the broken tile. As you noticed, none of those images corresponded to the broken tile.

As a final note, I’d like to mention that this issue occurs much more frequently on mobile devices.
I’ve tested it on both Android and iOS, and the problem persists on both platforms.

Allright, I can only reproduce it 10% of the time when quickly and erraticaly moving the camera just after changing the current panorama. In a normal operation : clicking an item in the gallery, wait 1-2 seconds for the image to load, then moving the camera, it never happens.

So I don't think I will take time to debug this. If it was reproducible 100% of the time why not, but here it seems to be a very rare edge case only found by QA testers :-)

Also did you try to update the lib ? There was a lot of performance related changes in version 5.11

[Mohammadf4f12]

I have used the latest version of the library in the demo. Also, this problem occurs much more in mobile. When using the virtual tour, the user usually moves between images very quickly with markers. As a result, the library creates many logs for the virtual tour
