title bars have "error while measuring font [windowtitle]"

[spiral4]

With the latest updates, when I open any window (Spells, Feats, character sheet, combat tracker, all of them) the log window pops open and I see the following error message:

[<date> <time>] [ERROR] Error while measuring font [windowtitle]

The error occurs on Open and Close of the windows. Looking at the windows, the title is either blank or some random text (once I saw 1d8+5, another time I saw what looked like text from another character sheet. It doesn't appear to impact game play, but is really annoying.

System config: AMD Ryzen 7 1800x, 32GB RAM, Windows 10 (latest updates), AMD Radeon v20.4.1 Graphics driver (Vega 64 GPU)

Welcome to the FG forums!

What ruleset are you running?

What extensions (including themes) do you have enabled?

[spiral4]

DnD 5e

theme: D&D theme v1.0, language fonts v1.0
I am not the server admin, so I am not sure what else to look for.

Ruleset in the chat view: 3.3.11

there are 2 homebrew modules added by the admin, plus the Rob Twohy modules, the DnD core modules, Sword Coast, Mordenkainen's Tome of foes, a bunch of custom maps, items and effects coding (all 5e srd, basic rules, and core rules, under All Rules - all modules except Curse of Strahd, Elemental Evil Player's companion, and wayfinders guide to eberon).

Thank you.
