--- Comment #6 from Henrik Harmsen <hen...@harmsen.se> --- Some more troubleshooting information. My previous comment should be ignored because that was due to another problem which got fixed in krfb: "pw" plugin does not work at all in X11 so that is why it did not work. krfb now no longer enables "pw" under X11 anymore. However, I set up a KDE wayland desktop (in a VM) and I am now using that for troubleshooting. Using the "pw" plugin here, I get two different outcomes: 1. If "Portal" pops up a window asking what to share (as described in https://bugs.kde.org/show_bug.cgi?id=458191) then I can semi-successfully connect to krfb from VNC. However the client window has changed everything that is blue into yellow. Seems RGB got mixed up somewhere. This is the first time krfb has ever worked in any fashion on Wayland for me. So semi-success there. 2. If I restart krfb rather quickly, then "Portal" does not pop up a window asking what to share (maybe the answer is cached) and then I get the failure mode described here with the invalid window sizes. I don't even know what Portal is yet though. I'm attaching here a printout from krfb in the two modes described above. By the way I am using Kubuntu 22.10 for my testing, probably it doesn't matter. 1. ################################################################################ kdesrc-run Module: krfb Program: krfb Revision: b740b6518eef498e184a3ccfafc3ba854748531e Arguments: ################################################################################ krfb.krfb: Loaded plugin with name "pw" Initializing D-Bus connectivity with XDG Desktop Portal DBus session created: "/org/freedesktop/portal/desktop/request/1_63/krfb718875647" krfb.krfb: Using FrameBuffer: "pw" krfb.krfb: Starting server.
