Running Ubuntu 21.10 I select GNOME or GNOME on Xorg when logging in. Gnome version is 40.4.0.
I don't like a dock cluttering the screen, so I have installed vanilla-gnome-desktop and rely on Gnome extensions. For example, the excellent Desktop Icons NG (DING) gives me desktop icons to start programs and manage mounted network drives. To list running programs, I have installed Window List. The latter works well, with one exception: You can switch workspaces by scrolling the mouse wheel over the thumbnail pictures; unfortunately, the area to the right of the thumbnails is now not included as it used to be when this extension was positioned in the corner, displaying "n/m" instead of the thumbnails. See the attached picture, where the area now NOT reacting to the mouse wheel is given.
The reason I object to this is of course that placing the cursor in the corner is so easy to do.
I thought this would be a GNOME issue, so I contacted the people at https://gitlab.gnome.org/GNOME/gnome-shell-extensions to seek help. Unfortunately, the issue I raised there was eventually closed with the label Not GNOME: the developers could not reproduce this behaviour.
The question is: can I restore the scroll behaviour in the corner, and how?
Update:
Just to add to the confusion: I have three laptops, and on the third (an old HP Pavilion), there is no problem. The Thumbnails are displayed flush right there, and scrolling works.
I'm wondering if the graphics driver can somehow be the culprit. Don't know how to further investigate this, maybe a pointer from someone?
