1) Different in OS?
Both OS is windows 10 with latest version.
2) Different in Wallpaper engine setting? Different type of wallpaper?
I tried to remove wallpaper with wallpaper engine running, still not working.
3) Different in GPU's and its setting?
My GPU with AMD can run properly, but failed on the other PC with Nvidia GPU.
4) Different in display setting, ie resolution/scaling etc etc.
Both resolution are the same (1920x1080)
