Dell Chromebook 3445 screen flickering

I have a Dell Latitude 3445 on a Ryzen 5 7320 processor, everything works great in chrome os, all tests pass without any questions. But when I tried to install Windows, I got screen flickering, I tried reinstalling the drivers for the video adapter, but nothing helped, then I tried to install Fedora, but there is also this screen flickering, my question is - is there any way to fix it?

Now I installed chrome os again and everything is fine. In chrome os I have the touch screen working, but in windows and linux it doesn’t work, maybe it affects something, or is it something with the mrchromebox firmware?

Please help me out.

you were using the latest UEFI Full ROM firmware? or RW_LEGACY/Alternative bootloader?

Yes, I’m using the latest UEFI firmware. I installed it the day before yesterday and today I installed Chrome os again and everything works fine

On Windows and Linux there is screen flickering, I don’t understand why

me neither, and I don’t have one to test. No issue on Frostflow or Markarth AFAIK.

The display init is handled by the FSP blob, and it’s the same blob for ChromeOS and my firmware (unless AMD updated it for Google and didn’t publish the update). There isn’t really anything to tweak from the firmware side.

Let me know when there is a solution

Or do I just have to wait for the AMD driver update?

it’s not a driver issue. nothing can be done at the moment,

Ok, thanks for the answer

I wish I had just bought a sound driver for windows
