Thumbnail previews in Files/Nautilus only show when zoom is 150% or more

[Loïc Alejandro]

Ubuntu 18.04 LTS
Nautilus package: 1:3.26.3-0ubuntu4

I don't get thumbnail previews in Files (Nautilus) at the default zoom level when using List view.

If I select 150% in the hamburger menu the thumbnails are displayed, and they are displayed in Grid view at all sizes. They are also displayed in the Open File dialog, even though the icon size there is smaller than in Files!

Status changed to 'Confirmed' because the bug affects multiple users.

That's known upstream, https://gitlab.gnome.org/GNOME/nautilus/issues/398

OMG... just spent one hour trying to "debug" the issue, when it is an intentional change by Gnome... I hope they revert this, or that Ubuntu can override this setting.

I created a fix for this, with a new configuration option. I uploaded a diff here: https://gitlab.gnome.org/GNOME/nautilus/issues/398#note_493737

I don't know if Gnome will accept it, or what the process would be to include it in Ubuntu

We are probably going to follow GNOME is doing, having downstream changes specific to Ubuntu has a maintainance cost which we try to avoid (also going against the software writter and changing their project in a way they don't agree with is often leading to conflicts which we also prefer to avoid)
