Description

Using the latest 0.6.0-rc.5-1 release Debian package on a Debian testing/unstable system. Had issues with earlier versions and NFS due to not having eBPF module, but now that it bundles it, NFS works well, so I assume eBPF is working.

Today I noticed some weird sluggishness in Firefox that I intuited may be network issues, so I started a test ping to google.com in a terminal window while I continued browsing. (The ping did reveal some packet loss, I need to check the switches between me and my router as the router shows no dropped packets).

As I loaded up printables.com in Firefox, I got an opensnitch popup relating to the `ping google.com` process but it seemed to think ping was trying to send ICMP to a printables.com domain. Indeed, even now as I loaded the page to report this issue, I got a similar popup, again relating to the still-running ping command, but some unrelated IP that I presume has to do with GitHub.

So, in short, it seems Opensnitch is getting confused. I didn't react quickly enough to screenshot the popups but I found the event log portion where the printables event occured.

(The screenshot makes the UI look broken, I think that's just because I'm using qt5ct under Cinnamon to try and theme Qt sensibly, and I clearly have failed. Other Qt programs are having similar issues, it's not Opensnitch's fault, I just haven't gotten around to fixing it yet.)
