shadow mode @ wayland client: content drawn to just 1/4th of window size

[thomas725]

Describe the bug I'm connecting from a KDE Plasma Wayland client to a Cinnamon X11 server in shadow mode. The Window size seems reasonable, but the content of the desktop is only drawn to the lower left 1/4th of the window, but the mouse pointer is interpreted as if the whole window represents the servers desktop. So it is impossible to control like that.

System Information (please complete the following information):

• Server OS: Linux Mint 21.3 Kernel 6.2.0-32, Cinnamon Desktop
• Client OS: Manjaro, Kernel 6.6.32-1 KDE Plasma Wayland Desktop
• Xpra Server Version v6.0-r0
• Xpra Client Version v6.0-r0

I've recently upgraded the server from v3.1 but saw those warnings during the upgrade:

dpkg: warning: unable to delete old directory '/usr/lib/udev/rules.d': Directory not empty
dpkg: warning: unable to delete old directory '/etc/xpra/conf.d': Directory not empty
dpkg: warning: unable to delete old directory '/etc/xpra': Directory not empty

Is that maybe related to my new issue?

No. This is dpkg struggling to remove the old package - for whatever reason.

To workaround the window size issue, you can run your client with --opengl=no. It will be much slower, but should draw over the whole window.

thanks, that works! but as predicted, it's quite slow. but at least it works ^^ thank you very much :)

This should have been fixed in 6.1.x, please comment if not.
