Of course. I should have already sorry. I did not know how to word the title, considering the link is somehow between Guacamole, XRDP, and possibly Openbox or X?
Guacamole/GuacD - tested 1.5.4 and 1.5.5 Alpine: v3.21 Debian: bookworm (alternate system, same issue) xrdp: 0.10.1 (alpine), 0.9.21 (debian) Xorg-server: 21.1.6 (alpine), 21.1.7 (debian) Openbox: 3.6.1 (both) I have 3 test builds - a Debian box with xorg, xrdp, and openbox, an Alpine box with those three, and a different Debian box running Docker with an Alpine image closely cooresponding to the second box. All three show the same symptoms. No system has xfce4 (which I have had no issues using in the past). I get no error messages that I can find in guacamole or guacd, or Xorg. The guacamole connection will stay up for an unknown amount of time - it will not time out. Microsoft RDP Client works with all three test boxes. I have Firefox auto starting, and I can browse just fine. I just ran tcpdump on the Debian 1 host, and I see a storm of TCP ACK packets length 0, with rare SEQ if I try to do a mouse or keypress. But the screen will not update. I can try with another WM instead of Openbox next. Sent with [Proton Mail](https://proton.me/mail/home) secure email.
