Status: RESOLVED DUPLICATE of bug 1661192

(Core :: Widget: Gtk, defect, P2)

Description

[Wout B]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0

Steps to reproduce:

I'm using Firefox 77.0-1 (with MOZ_USE_XINPUT2=1 and MOZ_ENABLE_WAYLAND=1) and Sway 1.4-2 on Debian Unstable.

1. Enable autoscrolling.
2. Middle-click somewhere.

Actual results:

No icon indicating autoscrolling at the place of middle-click showed up.

Expected results:

Like in previous versions, an icon indicating autoscrolling should show up at the place of middle-click.

In bug 1638084 comment 6 the autoscroll icon was missing on Gnome Wayland on Ubuntu 20.04, too. I assume this is the regression range for it.
Sway: If I don't get a main process crash with recent Nightly, the autoscroll icon is still missing.

With Gnome Wayland on Debian Testing the autoscroll icon is just misplaced: bug 1640651

Sometimes it does in fact appear, but in a weird place. In most cases it doesn't appear at all though.
