Hi there
Thanks to both @bdsams and @Dr W for such a speedy response. 😍
To provide that 'missing' context (you asked for it so you're gonna get a full download! 🤣) - I've used Fences for many years, but I've never pushed it like this before. Generally I might have had maybe 3 fences and that was it.
But I also discovered virtual desktops fairly recently, relatively speaking (maybe 3 or 4 years ago) and since then I've been expanding and revising the way I work. I actually now have a dedicated virtual desktop for each of my work streams (General, Development, Video Editing) along with a dedicated Fences page for each, and I use a (very) hand-crafted AutoHotKey v2 script to keep my Fences page in sync with my virtual desktop (it's very cool and I might write up a suggestion for native support for this by Fences in the future).
Yes, it's a relatively new build. I have a little time off work at the moment so I'm taking the time to really set up my machine the way I want. 98% of the software installed was done so using UniGetUI (combines winget, choco, .NET tool, etc into a single UI) and it's pretty easy to extract all my software for you to peruse using UniGetUI (it's open source). I started this Windows install fresh (not an over-the-existing OS reinstall) toward the end of January this year. I can also multi-boot fairly easily as I use Windows' Native Boot from VHD functionality to run the OS from a virtual disk (VHDX) which is virtually identical to running on bare metal (1-2% reduction in disk IO).
It's a couple of years old now, but my machine is a Microsoft Surface Laptop Studio 2, so it's pretty gutsy - 13th Gen i7 CPU with 20 cores, 64GB RAM, dedicated NVIDIA GeForce RTX 4060 with 8GB GPU memory as well as a discrete Iris Xe graphics GPU from Intel. It ought to handle most things I can think to throw at it.
Here are the proper system specs:
Processor 13th Gen Intel(R) Core(TM) i7-13700H (2.90 GHz)
Installed RAM 64.0 GB (63.8 GB usable)
System type 64-bit operating system, x64-based processor
Pen and touch Pen and touch support with 10 touch points
And the Windows specs:
Edition Windows 11 Pro
Version 25H2
Installed on 21/01/2026
OS build 26200.7922
Experience Windows Feature Experience Pack 1000.26100.300.0
I installed the official firmware / driver pack for this Surface model from Microsoft, and I also installed NVIDIA App and am using the "Studio Driver" mode which recommended the latest NVIDIA driver for my GPU: NVIDIA Studio Driver Version 591.74 (released 5th Jan 2026).
I tried the Fences 6.4 beta as the release notes said it was more stable on multi-monitor setups (and it was listed as addressing a lot of the issues I'm having) but as mentioned the result was the same. I was just trying to see what worked. I rolled back to the 6.2 version but both times uninstalled using the purge bat file script.
Hmmm... I don't really have other software that deals with the visual elements of the desktop (such as "Wallpaper Engine" that you cited). Stardock is pretty much the only customization software I use. I do use DisplayFusion to handle the multiple monitor context, but I've previously used both Fences and DisplayFusion together for years and had no issues.
I'm not really sure I understand what you mean by "system extension". Do you mean customization software similar to Fences? If so, I just addressed that above. Maybe I will just pre-emptively give you that list of my installed software. I'll put a zip file ("Package Audit - 2026-03-03 03.00.zip") in the same Dropbox folder as my original thread. In the zip will be a "ubundle" file. To get the best experience you will need to install UniGetUI from GitHub, but ultimately it's just a JSON file with the list of software - the UniGetUI software will just present the best way for you to consume it, plus for everything that wasn't already on the machine with the OS, it'll give you all the package details, which package manager it was installed from and links to the developers' website or repository etc. It will even allow you to sort the list which will come in handy for you to analyze my system.
Apologies about assuming Fences wasn't a 64-bit app. It was sitting in the "Program Files (x86)" folder which is why I thought it must have been 32-bit. TBH, the display issues look like a classic memory address problem which is why I was so ready to believe it was a 32-bit app - I naively assumed Fences was having issues with addressable space within a 32-bit context... My bad.
Ok, I just took a software audit. And even though I've been using UniGetUI for over a month now, I'm still amazed.... You really should take a look at it's capabilities, and maybe even consider using it for your support desk workflow (I actually work as a CTO so understand typical SaaS / ISV vendor environments). For complex cases (like mine!) you could ask customers to install it and create a system software audit they can then give you. I literally created a full software audit (including PWA apps installed via browser!) in less than 2 minutes!
Over to you I guess... I have no more 'context' to give you! 😂
Cheers,
Paul
