Re: Brand New Laptop with Ryzen 4700U Vega 10 Screen Flickers

It didn’t impact WSL2 performance in any noticeable way for me. That’s the only virtualization I do on my system though.

Re: Brand New Laptop with Ryzen 4700U Vega 10 Screen Flickers

The flicker occurs on an idle desktop in Windows.

To stop flickering IOMMU wasn’t disabled system wide, only the Hyper-V setting. I hope AMD or Microsoft comes out with a fix soon, but for now (for me) it’s better then flickering.

In any event this is a defect and a potential workaround, not a performance tip.

I agree with you, it flickers while doing the most mundane tasks like web browsing or just viewing documents.

I hope that it's at least acknowledged by AMD and Microsoft. I have seen threads where this issue does not seem to occur on open source software in Linux distros.

I had no flicker in Linux but I wasn’t running any virtualization. I noticed other issues though which is why I installed Windows for now. I’ll try again once Fedora or Ubuntu have stable releases with a Ryzen friendly kernel.

20.4.2 is incompatible with Ryzen mobile 4000 series processors. If you are speaking of another version which actually is compatible, do let us know in the comments.

Try 20.9.2 which is the latest driver for Radeon graphics

I am currently on the same driver that you've mentioned. It still flickers, unfortunately.

Unfortunately given the mobile 4000 series are fresh it may take a while for the machine to stabilize.

Check to be sure your BIOS is updated regularly too

Are you saying that the flickers will resolve itself on their own? If that were the case, it should have gone after the first few days, they show no sign of letting up just yet. 

I am on the latest BIOS available to this laptop.
