Long zoom meeting done; now I'm back to this.

memfd refers to "Memory File Descriptor".  The file in question exists only in RAM and is a temporary file at that.
Command such as "restorecon" are useless for this.

ok.

I'm guessing it may be caused not by caja by xeyes.  But if you're not having any problems it would be something that I'd ignore.  I don't know if this would apply, but when the Alert pops up there should be a button for "ignore" beside the button for "troubleshoot".  If I recall correctly.

You remember correctly.

If I were having these alerts and wanted to do a little debugging I'd first run my sessions without xeyes.

I don't know how you installed your nVidia drivers.  But, I would check to make sure what I had were the
latest.  FWIW, I use the nVidia stuff packaged by rpmfusion.

I started out with the proprietary driver 8 years ago. 1 or 2 years later, as advised by this list, I switched to the kmod? package(s?) from rpmfusion. The rpmfusion stuff was installed the way members of this list instructed. I see the rpmfusion stuff patched during over half of my weekly patches.

I don't know if any of this helps, but here goes:
* The problem started after upgrading to f33.
* I have not noticed any problems with xeyes.
* The sequence of steps leading to the alerts is:
1. Using the command line in a terminal, download a Chinese music video. The resulting file has a name made of traditional (Taiwan) Chinese characters.
2. Launch caja.
3. Use caja to rename the file to something with all ASCII characters.
4. Use caja to launch the file for viewing. I think it's launching VLC for that.
5. View the file and, using vim in a terminal, make study notes.
6. In caja, delete the file.
In caja, for each file, there is a small icon, the name of the file, and meta-data for the file. In the case of video files, that icon is an image, a frame from the video. The factors that have been occurring to me are the traditional Chinese characters and the image icons. But why only the first time in a login session? That's what most puzzles me.

Tomorrow morning, I will try the no-xeyes test that you suggest.

Ignoring the problem is tempting, but I don't want to give up toooooo easily.
