Just installed displayfusion on a new PC I built after having used it for years on an old computer and the new version has gaps that show the wallpaper around windows. Not sure what is/could be different. I'm running a 55" 4k panel split into 4 displays. It's not especially harmful, just distracting and frustrating since it hasn't been a problem with this monitor with the old PC hardware.

Absolutely. It's primarily an issue with mail where it circles the whole window, but chrome the issue occurs slightly along the gap between the lower monitors.

Gave it a shot. It was already off but enabling and disabling it resulted in no change

Fixed the issue by installing a theme edit
