Bug Report - Cheat Engine taskbar icon only shows on primary taskbar

9 discussion posts
When using the Cheat Engine application on a multi-monitor setup with the latest version of DisplayFusion, the main window (and child windows) of Cheat Engine only shows its icon on the primary monitor's taskbar. Regardless of whether the window is manually dragged to another monitor or a hotkey is used to move it to another monitor, its icon will not show up on the taskbar of the monitor it was moved to.

To download Cheat Engine for testing, the following URL can be used:
https://www.cheatengine.org/download/CheatEngine7.2_MissingSetup.rar

This will download a RAR package which contains the CheatEngine.exe file and its companion files. I suggest using this package as opposed to the main download link on the download page (https://www.cheatengine.org/downloads.php) as it requires no installation (and the installer for the main download link contains promotional software "offers" which will be installed if not unchecked).

I've included a screenshot of my relevant DisplayFusion settings.


DisplayFusion Pro Version: 10.0 (Beta 3)
OS: Windows 10 Enterprise
OS Version: 20H2
OS Build: 19042.1083
OS Experience: Windows Feature Experience Pack 120.2212.3530.0

Hello,

Could you do the following to send me some more information about the application window that's having this issue?

  • Install one of our other apps, Window Inspector: https://www.binaryfortress.com/windowinspector (it's free)
  • Open the affected application
  • Open Window Inspector
  • Hover over the affected window with your mouse so that the affected window's info shows in the Window Inspector window
  • Press Ctrl + Shift + F1 to freeze the timer in Window Inspector
  • Press Ctrl + Shift + F2 to save the info from Window Inspector to a file
  • Send me the file from the previous step

Thanks!

Absolutely! I've included 3 files.

One with the window on my primary, center AOC monitor (labeled monitor #1 by Windows) which is an ultrawide running at 3440x1440.

One with the window on my left-side Dell monitor (labeled monitor #2 by Windows) which is a 1920x1200 monitor rotated into portrait orientation (so technically a 1200x1920 resolution).

Finally, the last file was taken with the window on my right-side Dell monitor (labeled monitor #3 by Windows) which is also a 1920x1200 monitor rotated into portrait orientation (so also technically a 1200x1920 resolution).

Let me know if you need anything else!

P.S. Just wanted to mention the one 'abnormal' thing I could think of in relation to this app and why it could possibly be acting differently than others. I'm pretty sure it is not relevant but in order for the app to work correctly with UWP/'Microsoft Store' apps (the app itself is used to view/analyze/modify any running app's process memory), special security permissions have to be added to the application's directory. Specifically, you must add a permission entry for the special/built-in user 'ALL APPLICATION PACKAGES' and give that user 'Read & Execute' permissions. I'm 99% sure this isn't the source of the problem as you do not modify the 'Owner' of the directory or change/modify any of the existing default permissions but I just thought I would mention it in case it was relevant. Thanks!

Hello,

Thanks for sending those over. That's an interesting note about the permissions. If you launch DisplayFusion as administrator, does the issue persist?

Does the application appear in your Alt+Tab menu as well?

Thanks!

Sorry I'm only just now getting back to you. Well, being that the DisplayFusion service is run with SYSTEM privileges, I don't think that should play any role. However, running the CheatEngine app with or without admin privileges makes no difference. No, unfortunately CheatEngine does not show up in the ALT+TAB menu either, regardless of whether its window is on my primary monitor or different one.
