Windows 11 Alt+Tab stops displaying apps on the secondary display when using DisplayFusion

What the title says. I want to use the Windows 11 native Alt+Tab, but if DisplayFusion one is set to "Disabled", the Windows 11 native one doesn't show any apps from the secondary display...

Same for Win+Tab. If DisplayFusion is loaded, it only shows the windows of the Primary display.

DisplayFusion Alt+Tab works like ass. I'm trying to Alt+Tab to Chrome, and instead of bringing the Chrome window to the front, it just keeps flashing on the taskbar... wtf is this behavior?

Hi Jesus,

When you have Alt+Tab disabled in DisplayFusion, do you also have the taskbar mode set to "Windows taskbar shows all windows, DisplayFusion shows relevant windows"?

What version of Windows 11 are you currently running as well?

Thanks!

I have "All taskbars show relevant windows"

Windows 11 Insider Build 25115, but happens with any previous version I tried since maaaany months ago.

Even if I totally disable Multi-Monitor taskbar the DF Task Switcher keeps doing that stupid taskbar flashing thing instead of bringing the selected app to the forefront.

Hi Jesus,

For the Windows AltTab, it will only be pulling from the Windows taskbars, which means if you have your taskbars showing relevant windows, anything on the non-primary taskbars won't appear. Changing your taskbar mode to "Windows taskbar shows all windows, DisplayFusion shows relevant windows" should fix that up.

For the button flashing, do you have "SetWindowPos: Disallow TopMost Calls" enabled in the DisplayFusion Advanced Settings?

Thanks!

I had it enabled, but disabled it 2 days ago and made no difference. Still the same behavior: apps like Chrome, Rambox or Total Commander keep flashing on the taskbar but they do not come up to the forefront.

Could you send me over a debug log? Here are the steps:

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • Reproduce the issue and note the time so we'll know where to check in the log file
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log

Thanks!

Here is the file, and here is a recording of the behavior: https://youtu.be/Od62hQZlXn0

This happens ONLY with DisplayFusion's Alt+Tab replacement. Both Windows 11 Alt+Tab and Classic Alt+Tab (forced in WinaeroTweaker) work ok.

Thanks for sending that over. Could you also send me a backup of your settings? You can grab them in the DisplayFusion Settings > Options tab, using the "Export Settings" button.

Thanks!

Thanks for sending that over. I tested this on my end with a normal Windows 11 build, and the Windows 11 insider build, but I can't seem to reproduce this on my end.

Do you have any other 3rd party applications that deal with window management that might be interfering here?

Thanks!

Nope. I don't have any other 3rd party window management app. And if I Exit DisplayFusion both Win11 and classic Alt+Tab work ok, why would that be?

I tried shutting down every single program that was loaded in memory, even basic stuff like mouse drivers, and it didn't make any difference...

Restarting Explorer doesn't fix it either.

But signing out and signing in again does...

I'm stumped on this one! How long does it take after signing back in before this issue happens?
