I\’m not sure if anyone has reported these bold boxes that I see all over Windows 10 and Windows Mobile… Or maybe people have reported it and I just have not seen it… I don\’t know how to explain it. There is no way to trigger it. It just happens sometimes. I see it in edge, the store, one drive, start screen etc. They really irritate me at times and make the OS seem very unpolished. Here are the screenshots:
I believe those are highlights so one can use a keyboard to navigate those options. Previous versions probably had either a slight blue glass effect or a subtle dotted box outline instead. I don\’t know off the top of my head how they\’re triggered though.
