There's a Windows issue where if the window doesn't have a button on the primary taskbar, it gets unregistered from everything, including the Snap functionality. We have this on our list to fix up, and if we're able to get it sorted out in a future update, we'll definitely let you know.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/stock-window-snapping-broken-on-non-primary-monitor-not-related-to-df-snapping-i-think/?ID=2787b9e8-b463-47c4-9ae6-0d93ed01ccd7#3 Thu, 23 Apr 2020 13:53:15 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/stock-window-snapping-broken-on-non-primary-monitor-not-related-to-df-snapping-i-think/?ID=2787b9e8-b463-47c4-9ae6-0d93ed01ccd7#3 DisplayFusion Affirmative, "All Taskbars show all windows" also does not have the issue.
Edit: Just as a test, "Windows Taskbar shows All, DF shows Relevant" does not have the issue.
"Windows shows none, DF shows all" refuses to even show the Snap bar, nor will it suggest windows to fill the second half of the screen. ]]> https://www.displayfusion.com/Discussions/View/stock-window-snapping-broken-on-non-primary-monitor-not-related-to-df-snapping-i-think/?ID=2787b9e8-b463-47c4-9ae6-0d93ed01ccd7#2 Wed, 22 Apr 2020 21:04:25 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/stock-window-snapping-broken-on-non-primary-monitor-not-related-to-df-snapping-i-think/?ID=2787b9e8-b463-47c4-9ae6-0d93ed01ccd7#2 DisplayFusion If you change the Taskbar Mode on the DisplayFusion Settings > Taskbar tab to "All taskbars show all windows," does that fix it up as well? ]]> https://www.displayfusion.com/Discussions/View/stock-window-snapping-broken-on-non-primary-monitor-not-related-to-df-snapping-i-think/?ID=2787b9e8-b463-47c4-9ae6-0d93ed01ccd7 Wed, 22 Apr 2020 13:23:40 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/stock-window-snapping-broken-on-non-primary-monitor-not-related-to-df-snapping-i-think/?ID=2787b9e8-b463-47c4-9ae6-0d93ed01ccd7 DisplayFusion What I mean is hold the Windows key, press Left or Right to make the active window snap to that half of the monitor, then select another window to pair it with. When you click between them, a thick black bar appears, and you can slide it left or right to change the ratio between those two windows.
It works fine on my Primary monitor, and on my secondary _IF_ DF is not running. Once DF is running, one application moves, but the other does not. My testing as been with Chrome and OBS Studio. 99% of the time, Chrome (trying to shrink it) will shrink appropriately, but OBS will stay at the halfway marker. Very rarely, OBS will change size, and break the Snap at the same time.
It seems to be related to the Multi-Monitor Taskbar, as turning that off has the windows remaining snapped together. ]]>
