Taskbar.dll crash

From time to time the Taskbar.dll crashes (inside of Explorer.EXE). Sometimes it can restart itself but not always and I have to manually restart explorer.exe through Task Manager.
Does anyone else have this with Windows 11? I do have two Monitors and mostly everything disabled in DisplayFusion, I only use it to rearrange/resize windows.

Strange, does the issue persist if DisplayFusion isn't running?

Thanks!

Today I didn't have DisplayFusion running and the explorer never crashed so far. It has definitely something to do with the DisplayFusion application I'd say...

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!

I've now set the corresponding options and waited until it happened again.
It should be directly at the end of the log, it happened at 22:38:30. I've then killed explorer.exe through task manager and started it again.

@WYRSCH69229 Do you have the full path to the DLL?

Thanks!

Well there's not that much information in the event viewer. It's just that underneath (in german):

Can you try adding explorer.exe into the compatibility settings in DisplayFusion (DisplayFusion Settings > Compatibility tab) and check "Disable Application Hooks", and see if the issue persists after a reboot?

Thanks!

I've tried this now and sadly it doesn't help. Taskbar still crashes after some time.

Okay interesting, can you try disabling all 3 hooks in the DisplayFusion Advanced Settings (Application, Polling, and Shell) and see if that helps after restarting DisplayFusion?

Thanks!

So far it finally didn't crash anymore! I'll post an update if it occurs another time.
Thank you very much for your help.

Okay interesting, can you run that over the weekend just to confirm that fixes it? If it does, can you re-enable those hooks 1 by 1, and see which one causes the crashes?

Thanks!

Sadly the Taskbar.dll crashed again, without re-enabling any of the hooks. Tho it seems like that it crashes not that often anymore but maybe that's just a coincidence.

Which version of DisplayFusion are you on? If you're not already on the latest beta, could you give it a try?

  • On the Settings > Options tab, enable the "Check for new Beta (newer, unstable) versions" option
  • Click the Apply button
  • Click the "Check for Updates" button

I've already updated to latest beta and still no change to this.

Could you try enabling the "Disable Hooking the Windows Taskbar" advanced setting and restart DisplayFusion?

Also, are you running an app called Explorer Patcher by any chance?

I've disabled the taskbar hook and at first it didn't crash for a couple of hours but then it does. I don't really see that there could be any solution, that's pretty frustrating...

No I've never heard of that application, so I am not using it.

We've just posted 10.0 Beta 13, I'm wondering if you could give it a try and let me know if this issue still occurs?

Thanks!

I've updated to latest Beta yesterday and today it crashed again after a few hours. Seems like updating didn't fix it sadly.

Could you attach a new copy of the DisplayFusion troubleshooting info from 10.0 Beta 13? There's something I want to double-check there.

Thanks!

Thanks! Still nothing interesting in the log unfortunately, I'm pretty stumped here. I will keep this open for now and if I come across anything I will keep you posted.

Still stumped on this one unfortunately! Do you want to try a few older versions of DisplayFusion to see if any of them don't have this issue? If they don't, we can try to narrow it down to a specific beta to see if we can track down the change that started causing this.

I've just installed version 8 and sadly the most important option is missing there as I use it mostly for saving window positions across all monitors.

Also I installed it on another PC a week ago and there I don't have any problems. It runs on the exact same Windows 11 version but is a laptop.

I've now tested Version 9.7 and the same problem occurs with that aswell.

This is a long shot, but the troubleshooting info shows that these DLLs are getting injected into DisplayFusion:

C:\Program Files (x86)\Xiph.Org\Open Codecs\x64\dsfOggDemux2.dll
C:\Program Files (x86)\Xiph.Org\Open Codecs\x64\webmsplit.dll
C:\Program Files\ffdshow\ffdshow.ax

I'm wondering if they could be contributing. Is there any chance you could try uninstalling those codecs to see if it makes any difference?
