Screenshot of the problem
When the agent name is too long to fit in the GUI we truncate it and add an ellipsis. However, it seems we don't take the added length that comes from the ellipsis into account. See the attached screenshot.
Fixed in r34724 that was done on bug 7136, and TAG screenshot updated in r34738.
The changes was made on commit r34720 actually.
This bug seems to only happen with some fonts. This bug emerge on Samuel's workstation (Fedora 31) and on macOS. Cannot be reproduced on Windows 10 and my workstation (Fedora 30).
Reproduced bug on macOS 10.15 with 4.11 client. And this bug is fixed in build 6350 client.
