Description Shawn W Dunn 2024-02-08 22:21:07 UTC

SUMMARY
When scrolling from older messages to newer ones, in a channel in Neochat, the scrolling *glitches* constantly dragging the scroll back to the same point in the chat, this behavior exists whether scrolling with the mouse scroll wheel, or using PgDn


STEPS TO REPRODUCE
1.  Open a channel in Neochat with chat history
2.  Attempt to scroll down to the latest messages


OBSERVED RESULT
Using the scroll wheel, in this particular example channel, it keeps dragging me back to a message at 09:43 Today.  If I attempt to continue to scroll, it snaps the scroll back to that same message at 09:43.   If I use PgDn, press it once, wait a few seconds, and then hit PgDn again, it scrolls down, but I don't pause between presses of PgDn, it keeps snapping back to that previous message

EXPECTED RESULT
When scrolling through chat history, the scroll continues to the bottom smoothly

This is happening much *less*, purely based on my observations, with 24.02.1   But it's still happening.

At least for me, this seems to have completely stopped somewhere in the 24.12.x releases.

Comment 6 Evan Maddock 2025-03-24 20:33:43 UTC

This still happens with extreme reliability for me on Solus, using Budgie and Xfce.
