The font used under icons in a normal Fence has a drop shadow. The font used in Portal Fences does not. These shadows render the text very hard to read if you have a sight issue. Changes in the System Font (via Winaero Tweaker) do appear to change the font but retain the shadow. This strongly suggests it is a Fences issue.
This has happened to me previously and I was able to override it but this time it appears here to stay
There have been various posts concerning this topic but so far as I can see there have been no answers forthcoming. I am on Win 11, Fences 4 - both fully up to date.
