An RDP session I frequently use died on me yesterday, first time I had remmina crash -- I'll see if I can reproduce and get a connection config or xfreerdp(1) equivalent as tester to share.
Backtrace says libcrypto/TLS, perhaps this is of interest. I'm on snapshots with pkg_add -u from yesterday: OpenBSD 7.5-beta (GENERIC.MP) #1695: Sat Feb 17 18:39:13 MST 2024 Core was generated by `remmina'.
