Comment (by Ephraim):
This seems to be related to fontconfig, so this problem might not exist on
Windows but Linux and MacOS only? And it might also depend on the versions
of the libraries used.
We've found .uuid files in other directories in linux font directories. No
idea why that is, but having a .uuid file in a torbrowser-container
doesn't feel like a good idea.
The file is created on first start of torbrowser as ./Browser/fonts/.uuid
and once it's created it doesn't change anymore so its mtime shows when
this installation has been started the first time and the .uuid contains
an actual unique uuid. Feels much like a tag.
I've tested creating a symlink in that place pointing to /dev/null and my
torbrowser still works fine without any sideeffects seen.
So my suggestion is to address this issue by creating a symlink
ln -s /dev/null ./Browser/fonts/.uuid
Currently using torbrowser 8.5.3 on debian sid (fontconfig 2.13.1-2)
I'm not using KDE, so it's not related.
