Question Screen 'juddering' in Windows 11

[JohnR1987]

I'm not sure if 'juddering' is the right word, but I've started seeing an annoying phenomena when accessing apps within Windows 11, including Chrome and the File Explorer. When I scroll, move windows around etc, the movement isn't smooth. However, I'm not seeing this in games.

I'm not sure if this would be a refresh rate issue or FPS issue, but I recorded a short video of what I'm seeing here: https://www.loom.com/share/b06d4a6e95f84328a69eabb0f5eb73eb?sid=96839e4e-4ac3-4cb0-9abf-d13d2fccc049

I have two displays (details below) and see it on both.

I've had the PC for about 6 weeks and this is a relatively new issue. PC spec below:

Monitor 1: MSI Optix G27C4 (connected to GPU HDMI port)
Monitor 2: Samsung 22F350 (connected to motherboard HDMI port)
CPU: AMD Ryzen 7 9700X
CPU cooler: PCS FrostFlow 240 Series
Motherboard: ASUS® TUF GAMING B850-PLUS
RAM: 64GB Corsair VENGEANCE DDR5 5200MHz CL40 (2 x 32GB)
2x SSDs: 1TB CORSAIR ELITE MP600; 2TB CORSAIR CORE XT MP600
GPU: 12GB INTEL ARC B580 LIMITED EDITION - up to date drivers
PSU: CORSAIR 650W CX SERIESTM CX-650 (brand new)
OS: Windows 11

EDIT: Okay so I've just played around and it seems to be happening when YouTube is playing on my Samsung monitor that's connected to the HDMI port on the mobo. It then stops when I move the tab onto my MSI display.

What BIOS version are you on for your motherboard? Connect all your displays to the discrete GPU(using an adapter if necessary), then disable iGPU in BIOS, run DDU to remove AMD and Nvidia GPU drivers in Safe Mode.

Since you bring up a concern, what refresh rate are you on for both monitors? On a side note, the sweet spot for an AM5 platform is a dual channel DDR5-6000MHz with tight latency ram kit while I'd have also looked into a higher quality PSU for your rig overall.

In answer to your two questions:

BIOS version: 1028 x64
Refresh rate on MSI monitor: 60Hz
Refresh rate on Samsung monitor: 59.94Hz

I couldn't actually see an iGPU setting in the BIOS though...
