At our organization, we use Royal TS (current version 6.1.60731) to manage our various RDP and SSH connections. I have also personally used DisplayFusion for a long time for the multi-monitor taskbar features.

Whenever I open Royal TS from a DF v10.0 pinned taskbar item on a multi-monitor taskbar, some weird behavior is exhibited. Royal TS will open fully maximized (desired state), but will then resize down to not maximized a few seconds later. The title bar button for Royal TS will show it maximized but it is not. You have to actually minimize it then re-maximize before it fixes. You can see the behavior in this video link in the protected attachments.

I can pretty consistently reproduce this issue from the DF multi-monitor taskbar pinned item starting point. If you start Royal TS from a Windows start menu or a Windows native taskbar item, the behavior is not exhibited. It opens on the secondary monitor, with a multi-monitor DF taskbar, maximized and stays that way. This behavior did not always happen, though I cannot pinpoint the exact version of DisplayFusion, Royal TS and Windows where it started. My Windows version is Win11 Enterprise x64 22H2 22621.2134. I noticed the behavior back in Windows 10 as well.

Royal TS support claims that this is a DisplayFusion issue. I am hopeful you can provide a suggestion.

Thank you in advance for any help!

Hi Owen! This was indeed checked, and disabling it resolved the issue! Thank you so much. I believe Royal TS somewhat recently implemented their own app logic to better remember monitor location/size, so I bet these were conflicting. Thank you again.
