I have been trying a fresh install of both Bookworm and Trixie on a Pi 4. I am using a VNC Viewer for Windows 11 on the same LAN. Openbox/X11 (hence RealVNC Server) on Bookworm/Trixie works OK. But Wayland/Wayfire and Wayland/Labwc on Bookworm/Trxie (hence WayVNC) have a bizarre problem.
WayVNC works OK for an hour or two, then apps start getting spurious input. Specifically, endlessly repeating backslashes appear in app input fields when I click on them. It is as if I were holding down the backslash key. (I have once seen single quotes repeating instead of backslashes.)
Once this starts happening I can press any key to stop the input. However, it then happens again the next time I click on the input field. I have seen this problem with various types of apps: text editors, web browsers, Java apps, etc. Curiously, terminal emulators aren't affected. This might possibly be because I have "kb_repeat_rate = 0" in ~/.config/wayfire.ini.
Once this has started happening, the only fix to to disconnect the VNC Viewer and then reconnect it. Things then work for a while until the problem repeats. The problem happens with both RealVNC and UltraVNC Viewers on Windows, so I think it's a server-side problem
I don't think this is the oft-reported problem of lost or delayed packets causing repeated keystrokes. The repeated backslashes happen when I just click on an input field, but without touching the keyboard. The Pi and PC are also on the same LAN.
The fact that RealVNC Server with Bookworm/Trixie is free from this problem rather points the finger at WayVNC. Any inspirations?
