I'm currently seeing this problem (does not happen ALL the time, but most time), is when I have documents in my DockingManager. DocumentsSource is binded.
The issue is, sometimes when i undock one of the documents, (either floating or side by side), and have focus on the Floated document, the docked document becomes blanked and vice versa. This is a problem now because undocking becomes useless as I cannot see
both item as once.
This also occurs for side by side documents in the same manager.
Has anyone also seen this issue?
Thanks and Regards,
