With the default XFCE <kbd>1x</kbd> window scaling, xlarge thumbnails look like this:  But when going in XFCE's <kbd>Appearance</kbd> > <kbd>Settings</kbd> and setting Window Scaling to <kbd>2x</kbd>, then zooming to get the same grid size (as shown by the blue background on the selected file matching with the previous image), thumbnails use the large size instead of xlarge:  This issue applies to further zoom levels. I think either the thumbnails should be bigger or the grid should be smaller, in order not to waste screen space. Specs: - Debian 12 XFCE edition - Thunar 4.18.4
