Issue with rendering screen content on scroll

[rishivanukuru]

Hello!

I was trying to set up this plugin on an Android phone, but there is a small issue where the content of a page is not being displayed when scrolling down a page. There are no issues when scrolling up. I have included a GIF showing this behavior, and the details of my setup are as follows:

Implementation: Browser Prefab using Webview (not Geckoview)
Unity Version: 2021 LTS
Android Device: Google Pixel 7 (OS 16)

Thank you for looking into this!

I'm also having similar issues.
Additionally you can scroll a page infinitely downwards (if you use the scroll API directly) which probably shouldn't be happening either. Same goes for scrolling upwards, but at least it doesn't scroll past the content.

I’ve found a way to avoid the rendering issue that occurred during scrolling. I keep an exact proportional relationship between View Size (1920×3000) and Tex Size (960×1500), and I also adjust the RectTransform height so the visible area properly matches the rendered texture. With this setup, the content no longer shows artifacts or unrendered areas while scrolling.

At the moment, scrolling downward behaves as if it were infinite, but this can be easily corrected with a small script that limits the scroll based on the actual content height.

I hope this helps.

Same here on Meta Quest 3/3s when using Android WebKit (chromium), when using the Gekko view everything renders properly when scrolling.

Thank you for your report. Please accept my sincere apologies for the significant delay in my response. I have implemented a temporary fix for the reported issue (since this is a fix on the native plugin side, please refer to the following issue for details). In summary, I suspect that the problem was caused by internal processes within the Android WebView.
