If i right click a file in Thunar and select open with and choose another program i get a long list of programs to open the file with.
But in this list is also:
Pop art squares
Since these are screensavers or screensaver themes i guess they are not made for opening other files.
So i suggest changing the .desktop files so they dont show up in the list.
The 3 .desktop files are inside;
So maybe Type=Application can be changed to something else to exclude them from the list of applications. Just guessing.
I dont know if Thunar just shows all .desktop files inside /usr/share/applications/ in the list of applications or if it have a filter so not show the things that are not for opening files.
All the things from Settings Manager are also in the list like Power Manager etc.

Hide screensaver themes from 'Open with' options (bug 15531)
Thanks for the bug report! I was able to reproduce and applied the above fix to hide the options from the Open with menu while still showing them in the screensaver options.
Where can i read about "Hidden="?
I dont see it on https://specifications.freedesktop.org/menu-spec/menu-spec-1.1.html
It's on https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html#recognized-keys
Technically I should have used NoDisplay, but it seems Thunar doesn't honor that setting in the Open With menu.
If NoDisplay is meant for that then i suggest we use that.
And then i can create another bug to get Thunar to honor it.
