I have not deleted any fonts recently that I am aware of, nor have I changed OS fonts... other than whatever applying a Windowblinds skin might do. Going through my list of skins, some cause the issue and some don't. I have a feeling whatever it is for me is tied to certain types of skins (the UIS type), though I'm no expert on this. Here are some examples:
Skins such as Aero Clay and Wall don't exhibit the issue.
But more "advanced" skins, such as Aero Station, Arsenic, Precision (my current favorite and the one in the screenshot above), Sublime, and Tinted all suffer from this issue for me. Pretty sure this wasn't always the case, but not sure exactly when it changed.
Thanks for your suggestions!
