Tampermonkey toolbar icon in Safari 13 should be rendered correctly just as it was in Safari 6-12.
The icon is rendered in a mistaken way, much more slim than it should be:

Tried uninstall and re-install Tampermonkey MAS version, yet nothing changes.
Probably a HiDPI/Retina related problem? I need to get a macOS running at a retina display first...

In 2015early MacbookAir(No Retina, macOS 10.15, safari 13.0.2), the icon also display in a mistaken way.

Me too, on a retina and non-retina mac
me too, twisted icon XD
Same here
me too, macbook air 2015.
Same problem in Original display and second display (monitor ultrawide displayport).
In the toolbar looks the same problem. See this photo. ↓

I was able to persuade my virtual machine to install macOS 10.15 to reproduce the issue. 🤓
Fixed at 4.9.6055 which was reviewed some minutes ago. 😅
