Outline node icons not showing in Win7 Classic

Hello, I'm not sure when I lost them (possibly after version 16.6) but on Windows 7 Classic theme the node outline icons are missing. I switched to Aero just to check.. and sure enough they were there! Classic theme: Aero theme: Okay, thank you!

I reproduced the issue, and it will be fixed on the next version. Thanks!

Awesome, many thanks!
