I just bought a new ASUS Vivobook S14 M433IA that has Ryzen 4700U and Vega 10 a few days ago. However, from the day I bought it, it already has screen flickers that happen randomly. The flickers happen only for a split of second, however it is kind of annoying. When I changed the driver to the latest AMD Graphic Driver, it actually got worse, with screen flickers happening even more often and sometimes the screen still has garbage leftovers from the previous frames, or for a split of second, half of the screen blinks white. I believe this is a driver issue since the laptop is new and when I changed the driver to the latest, it actually got worse.
Currently I am using the driver provided in this link https://www.amd.com/en/support/kb/release-notes/rn-rad-win-ryzen-mobile-4000 Though the flickers still happen, just a little bit better than the latest driver.
Does anyone know the fix or is it really a driver issue?
I have the same issue. I have an Asus Vivobook S15 which has Ryzen 4700U with Radeon Graphics.
I also believe this is a drivers problem. Removing the drivers also removes the flicker for me but at the cost of poor resolution and no external display. I installed Ubuntu on the laptop and that didn't suffer from flickering but the external display doesn't work.
I am now trying to get it replaced for a laptop which doesn't have AMD graphics, which will likely be an Intel CPU laptop. I am so sad about this because the 4700U is amazing.
Yeah, I already tried uninstalling the AMD driver on Windows 10, and ran the laptop using Windows 10 generic display driver, and it ran smooth without any flicker issues, though it lacks the features provided by AMD. Then I decided to use Manjaro Linux instead, using the provided opensource driver, and to this day I have not seen the issues at all. So it definitely is AMD Display driver's fault. So please AMD fix this issue.
I am glad it worked out for you. I ended up replacing the laptop for an i7 one (can't afford Ryzen CPU + Nvidia graphics) and I already feel how much weaker the i7 is. Hopefully, AMD fix the issue soon
I have seen this with windows 10 v 2004, it seems to be the WDDM 2.7 attempting a graphics reset which suggests a miniport driver issue.
I've had the same issue, with the same model of laptop, so it may be an ASUS problem, but i hope that AMD resolves the issue. removing the Display Adapter Driver seems to have fixed it but i am now unable to use OpenGL, which is critical for me, so i may move to Linux
Hi, yesterday I received a new ASUS S15 M533 with Ryzen 4700U and it suffers flickering from the beginning when in battery. I raised a call with Asus support and in the meantime I tried your suggestion to disable SVM in BIOS, and IT WORKS, thank you very much!
Disabling SVM stopped the flickering. I was also able to stop flickering with SVM enabled in BIOS by disabling Hyper-V with "bcdedit /set hypervisorlaunchtype off".
I do need Hyper-V to work for WSL2, so I'm sending bug reports as well.
EDIT: I found that disabling IOMMU was sufficient to stop the flickering. I re-enabled Hyper-V with bcdedit /set hypervisorlaunchtype auto then I explicitly disabled IOMMU with bcdedit /set hypervisoriommupolicy off
Of course disabling IOMMU is not ideal, but it is an improvement.
