I know this is a minor thing, but I use Parrot Sec daily and it drives me crazy after years! 
The sound icon is simply too large. and the Ethernet icon is way too small. OpenSnitch is looking blurry. It cleary is a theme issue because the sound icon of Parrot HTB Edition looks nice and it just uses a more clear Mate theme. I prefer using the HTB Edition just because of this.
I know it is eye candy but it just bothered me way too long. Sorry for this!
Update: If I remember correct in early 5 Versions this issue wasnt present.
Update 2: Changing the theme to ara-dark, the size is correct.
