The scroll bar of the second and subsequent columns does not work properly.
Also, if you move the scroll bar of the first column up or down, the behavior will be abnormal.

Hi!

I wasn't able to reproduce the issue on Firefox 88 or Firefox Nightly 90.0a1

Could you check if it occurs in safe-mode? Here is a link that can help you with that:
https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode?redirectslug=troubleshoot-firefox-issues-using-safe-mode&redirectlocale=en-US

If it also occurs in safe-mode, please also check it on a new profile. Here's how:

Thanks!

Hello Peter,
Thank you for your advice.

First of all I must apologize, the mention of the first column was my misunderstanding. This problem is only about second and subsequent columns.

I tried them, and identified the problem is related to my environment.
But the result is somewhat weird. At safe-mode, no problem. But at new profile (of course no addons), same problem happen.

I found a topic on reddit that mentions about same problem.
https://www.reddit.com/r/firefox/comments/csnedm/tweetdeck_scrollbar/
The phenomenon looks the same. It says to turn off hardware acceleration, but nothing has improved for me.

I probably found a workaround.
Turning "gfx.webrender.force-disabled" to "true" solves this problem perfectly.
I think this is a bug related to WebRender.

Since the issue doesn't occur to you with WebRender off, I'll set the component in order to get this looked at by the appropriate dev team.
Please add your about:support information into a comment below.

Thank you for looking into it!

Might be same as bug 1576770

See Also: → 1576770
Summary: Scrollbars does not work properly. → Scrollbars does not work properly on tweetdeck
Severity: -- → S4
Depends on: 1576770
See Also: → 1719913

This is almost certainly the same issue as bug 1576770 and bug 1719913.

Please see bug 1576770 comment 26 for details, and bug 1576770 comment 28 for a workaround that doesn't require disabling WebRender.

A fix is up for review in bug 1719913; once that lands on Nightly, we should double-check that it fixes this, and then we can close this bug.

@yneko, Firefox Nightly now contains the fix for bug 1719913. Could you try it please, and let me know if the issue is resolved? Thanks!
