Grid view in the file chooser? In my Ubuntu 20.04 system, it only supports standard list view with preview pane on the right side of the dialog.
Gnome throws a huge chunk of functionalities away in favor of UX on version 3, which alienates most of their power users but make it easier for new users to jump in with their mac-like ui.
It is strange to me how different people have different experiences. I wonder how much is hardware / driver related? In my case I have an AMD video card, and my system runs for weeks at a time (I reboot when applying kernel updates is all). Also had very good stability on my Thinkpad X2 Yoga (Gen 2) -- this one with the integrated Intel graphics.
I run Fedora, and update to the latest release about a month or two after it is released. Mostly because my job is with RHEL / CentOS, and Fedora keeps me up to date with what will be in the next RHEL major version. However I should correct my previous statement, that I have weird stuff happen with Wayland, and I give it a shot periodically but switch back to X11. (In my case, "weird stuff" is things like desktop screen sharing not working with MS Teams, or having HiDPI scaling interacting badly with older style X apps such as OpenSCAD -- in that case with Wayland the cursor has a hard time grabbing window edges).
The Linux (Gnome) UX is miles ahead of Windows.
I genuinely wish I could have Gnome on Windows.
