Also, I recently did a clean Win 11 install with exporting my settings and importing them after. The issue is still there.

If I turn on auto-hide on the DF taskbar the flashing does not happen when the taskbar is not on screen. It seems to only occur if the taskbar is visible, I can still cause the flashing to happen if I quickly move my cursor between the taskbar (to make it visible) and the 'critical separator bar'. ]]> https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#10 Fri, 16 May 2025 13:17:33 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#10 DisplayFusion If you turn auto-hide on for that taskbar, does that change anything? ]]> https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#9 Mon, 12 May 2025 18:18:26 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#9 DisplayFusion I don't use anything else like that, only DF.

I just tried this on my main display and it happens there too. I'm attaching a video of it. It seems to me that when that "adjustment bar" appears that lets me adjust the window ratios, that's when the task bar clips over from the secondary monitor.
I'm guessing you are not able to reproduce it? ]]> https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#6 Thu, 08 May 2025 18:16:12 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#6 DisplayFusion If you use DisplayFusion to add a vertical split on that portrait monitor, and then align your windows within the splits, does the same thing happen? ]]> https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#5 Tue, 29 Apr 2025 14:05:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#5 DisplayFusion I'm on Win11 24H2, no updates available in Windows update.

I wonder if it's a mix of Windows/.NET Framework/graphics driver causing it, can you make sure those are up to date and see if the issue persists? ]]> https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#3 Thu, 24 Apr 2025 18:42:39 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#3 DisplayFusion Hi,

I've done the steps you requested. The timestamp of the event should be 20:39. ]]> https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#2 Thu, 24 Apr 2025 17:56:59 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/taskbar-from-secondary-monitor-appears-on-top-of-primary-for-a-moment/?ID=0196681c-392d-73d6-a2e1-c0fb56fdb041#2 DisplayFusion Could you send me a debug log?

I'm using a multimonitor setup (1 landscape and 1 portrait) and the taskbar from my secondary montiror (the portrait one) flashes for a second near the top of the screen on my primary if I do a specific thing. I usually have 2 apps open on my secondary monitor, the screen is essentially halved between them. When I pull the cursor over them, and the cursor changes to the 'change the size of this window arrow' that's when the taskbar flashes on the primary monitor. I recorded a video of the thing, I'll attach it here.

Any ideas what could be causing this? The flashes are quite distracting when moving the cursor between the applications. ]]>
