I have been using Fedora for some years now and I never had any problem.
Then I moved from nearly perfect Fedora 39 to Fedora 40.
So far I got:
Icons are too big, double size than 39, seems like something is wrong in auto-settings for my display resolution and size.
Gnome Software alerts about any software I install going to be in US English and it is false, they all come with the correct language.
GIMP crashes on exit and throws a segfault error with a sort of debug-report window, it does not happen if I manually close each single image before closing GIMP. It seems it has been reported many times already.
Dejadup cannot connect to Google Drive any more, error already reported and maybe fixed but until Dejadup gets updated i don’t have my backup.
Gnome Tweaks cannot set fonts any more.
They aren’t major issues and I know they don’t depends on Fedora itself but given there isn’t any major change from 39 to 40, I reinstalled 39 and everything works.
I don’t know, maybe Fedora releases are too much cutting edge for “common” software to keep up, GIMP for example looks like it is still on GTK 2.x.
It’s been a while since I closed GIMP like that but I can also reproduce that today on F40
I don’t have that issue on F40 GNOME, but I’m on a 1080p screen 100% scaling. Last I tried fractional scaling it was blurry.
I had an odd scaling issue back with KDE Plasma 5 where it would only scale some things if I force-used the AMDGPU Xorg DDX driver instead of the modesetting DDX on Xorg. Afaik I don’t think this would be an issue on Wayland sessions, and I didn’t have that inconsistency with GNOME on Xorg regardless of the DDX driver.
If you know the fonts you want, I’d recommend using gsettings, just in-case of situations like this where the GUI setting is all of a sudden gone. If you go back to F39, I’d recommend getting the gsettings set values for them and saving them somewhere to use again later.
The problem with big icons comes from a “clean new install” without any changes.
Mine is a poor display of 1366x768 on a Dell Inspiron with Intel GPU, the PC came with Ubuntu pre-installed so I don’t think it can be any exotic hardware configuration, it looks more like either some Gnome bug or Gnome feature. I am comparing f39 and f40, liking f39 size more but who knows.
I have considered possible fixes and keeping f40 despite those relatively minor issues. GIMP still works and I can avoid crashes by closing images before closing GIMP. I don’t really need to change fonts. The real issue is Dejadup unable to connect, because I don’t really have any easy alternative for automatic backups on GDrive.
There isn’t anything that makes the desktop unusable.
In the same time I don’t see any good reason to use f40 instead f39 where I don’t have any issues at all. Even less when I think of updgrading other PCs where I could have the same issues and possibly more. It would be a waste of time to revert again to 39.
I haven’t tried GDrive on Linux aside from quick transfers from a browser, but I use Keybase and its cloud file management works fine on GNOME (Keybase exposes the public and private folders and they show up as regular folders on Nautilus).
I recall some project on GitHub that had command-line methods for hooking to a GDrive and handled logging-in and stuff but also presented the files on file explorers. I’m not sure how active Dejadup is (I heard of it only on an older Ubuntu release), but I wonder if there’s a different tool available for GDrive on Linux?
I saw the error in Dejadup has been reported and a patch has been already submitted and accepted.
From what I could get from it, it seems there is a third party library that processes some data and was expected to give some output, the output is not what Dejadup likes and so it throws and error and the connection to GDrive fails. The patch makes sure unexpected data is properly managed. Dejadup developer wrote he intends to investigate and ask upstream about the said library.
I guess something changed from f39 to f40.
Dejadup looks like it is actively developed and there is a 46beta version, pending 46.
Actually GIMP is also being developed and there is a GTK 3 version pending but it is a much bigger and difficult software so who knows when and how.
Yes there are other hosting solutions for backups and other ways to access GDrive. It is a matter of evaluating the work needed and the benefit that comes from it. Like I said, staying with f39 requires zero additional work.
I forgot another issue with Fedora 40.
Several areas of Gnome stay in english despite most of it comes with the correct language. There are some sub-menus in “gnome settings” and some other items here and there, for example “empty trash” in “file”.
Maybe that is somehow related to the alert given by “gnome software” when installing new applications about everything being in US english (which is not, BTW).
