Hi Guys,
I've had my HP Spectre x360 Notebook for almost a year now and l was running Object Desktop apps (like, most of them), and everything went slower and slower until W10Pro64 crashed entirely... Very frustrating... anyway, after running full hardware tests with HP support they declared the hardware was fine and suggested scrubbing to factory and starting again, which I did.
I was far more cautious installing additional software after recovering all my data from backups (this is why you take backups, people), and installing all my business-critical software.
Then I started reintroducing my OD software one at a time and testing between each module install. Curtains - fine, changing themes is great! WindowFX - fine, love the open/close animations and dulling of non-focus open apps. Fences - all good, nice tidy desktop again. SoundPackager - all good, now my Notebook sounds nice.... so far no impact on performance.
Then I installed Deskscapes (v 10.03 for reference). Even with a very simple desktop running like "Fences - by Azdude" the performance DIVES. My business apps take forever to change between open dialogs, changing between apps is laborious... I checked the Task Manager and "DSHost Application" is only running at around 5-6% CPU... Nothing else is high CPU consumption either...
When I pause Deskscapes, my performance returns to normal... resume deskscapes and it tanks again. Uninstalled the app, downloaded again and reinstalled - identical crap performance when running.
My Windows details are:
Edition Windows 10 Pro
Version 20H2
Installed on 2/10/2020
OS build 19042.804
Experience Windows Feature Experience Pack 120.2212.551.0
Has anyone else had issues on HP Spectre x360 specifically or with this combo of OS and Deskscapes?
Any ideas on how to overcome it? I used to enjoy my animated desktops... 
Thanks heaps,
Philip
