This is mostly fixed in the next development release of Ubuntu. Ubuntu 23.04 is not a Long Term Support release but will be released in April.
I am leaving this issue open because although the thumbnails are larger now, I don't see a way to change the thumbnail size. ** Also affects: gtk4 (Ubuntu) Importance: Undecided Status: New ** Changed in: gtk4 (Ubuntu) Status: New => Fix Committed ** Changed in: gtk4 (Ubuntu) Importance: Undecided => Wishlist ** Changed in: gtk4 (Ubuntu) Status: Fix Committed => Triaged -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1175608 Title: Thumbnails too small in 'open file' dialog nautilus Status in Nautilus: Expired Status in gtk+3.0 package in Ubuntu: Triaged Status in gtk4 package in Ubuntu: Triaged Bug description: When trying to upload image files to e.g. websites like marktplaats.nl (kind of ebay) I get very, very small image thumbnails. There seems no way to enlarge these thumbnails. All options only work if Nautilus is used stand alone, but not with the open file dialog that is being used to upload files. I have attached a screen dump just to show what I mean.
