Ohhhhh... that's a huge problem. I was thinking to install this plugin with the border radius. But now, that will be a hindrance.
I also have the same problem, it is a clean hyperjs, only with the plugin, I am using Ubuntu 20.04 with the KDE Plasma environment, if you have to install any package with apt please advise

I have not found a way to get rid of the window background at the moment. This seems to be a Electron problem.
If anyone has an idea on how to do it, please let me know.
Having this issue as well. On Windows 10.
I just tried it under Windows 11 with Hyper v3.2.3 and it looks like the black tip is gone.

Can someone confirm this?
But it still is not possible to change the outer radius.
no work linux,
I use Manjaro, - Gnome Shell 42 (wayland)
