Active Xpra Launcher session icons are shown separately on Windows 10 taskbar even when the taskbar becomes full. They could be shown collected together to save space, like normally happens when running multiple instances of the same program. Perhaps something in Launcher is preventing this from happening.

This is working as intended, see #799 for details.
You can turn off this behaviour with the environment variable XPRA_WIN32_GROUP_LEADER=0.
But then all the windows will be grouped under the same xpra taskbar entry, no matter how many xpra connections you have or how many applications run on the server side for each connection.
