Scrolling Behavior Issue on iOS Netskip #1

Open sweetpufferfish opened 5 months ago

sweetpufferfish commented 5 months ago

Description:

When scrolling from the top to the bottom of a page quickly an unusual shaking or movement occurs when reaching the end of the page.
The shaking effect gives the impression that the window is still scrolling even though the user has reached the end of the page.

Steps To Reproduce:

Open the browser on an iOS device.
Navigate to a webpage that requires scrolling.
Scroll from the top to the bottom of the page.

Expected Behavior:

The scrolling should stop when reaching the end of the page without any shaking or additional movement.

Actual Behavior:

As described it's shaking.

Environment: iOS version: 17.5.1 Device model: iPhone 12,1 Browser version: 1.1.1

Thanks for the report. I can reproduce it, and I'll work on getting it fixed for the next release.

The fix has been submitted to version 1.1.2 of Net Skip. Once it is available, please try it out and let me know if it solved the problem.

Thanks again for the detailed bug report.

Thank you for addressing the issue very quickly in version 1.1.2. While the top to bottom scrolling problem has been mitigated, I am still experiencing it on some pages like webkit.org. The problem re-occurs when scrolling down from just above the bottom and then quickly pulling down.

I've got very minimal coding experience but enough for me to have taken a closer look at the snippet of code right here containing the changes:

https://github.com/Net-Skip/netskip-app/blob/33d7fa652b9909a259cc2e9fddc384add06344ab/Sources/NetSkip/BrowserTabView.swift#L115-L125

The problem persists as the bottom bar seems to cycle between show and hidden states when the scroller (bounces, hits?) at the bottom of the page. This behavior causes instability and affects the user experience, despite the changes made to the URL bar visibility logic. Perhaps a different approach could be considered. Maybe, a debounce mechanism or some further threshold adjustments.
