Glitch effect on side of screen

[Mountains Away]

When I use an animated wallpaper the side of my screen has some sort of glitch effect. This only seems to happen when there is movement on the left side of my screen.

Any help would be much appreciated!

If you have a laptop with multiple graphics cards, try assigning wallpaper32.exe from the installation directory to a different graphics card in Windows: https://www.onmsft.com/how-to/how-to-set-per-app-graphical-performance-settings-in-windows-10 and fully restart the program.

If that doesn't help please share this full log by following the guide: https://help.wallpaperengine.io/en/debug/scantool.html

Thanks. Please try updating your Intel graphics drivers to be sure you have the latest one since the issue is definitely somehow connected to Intel GPUs.

Do you have this issue with both your monitors?

What happens if you disconnect the second (1080p) monitor and restart the PC, does that make any difference?

Yes I have the issue on both of my monitors.
I tried both of your suggestions, but neither seemed to work.

As far as we know, this seems to be a bug related to some specific Intel Iris graphics chips that we cannot fix from our end. The video playback is entirely handled by Windows. You can try and use LAV with DirectShow as outlined here:

Alternatively, you can switch to another wallpaper type for now (Scene or Web), as only video wallpapers suffer from this driver issue.
