Intel Arc A770 artifacts and flickering on Google Chrome and Microsoft Edge

[destroyboot]

Hi,

Today I bought myself an Arc A770 16GB (for gaming) and did not do a lot of tests as of yet, before running into a rather large issue. None of my installed browsers are usable with this graphics card. Everytime I perform the action that moves/changes anything on the screen in the browser, be it scroll or click, the screen flickers and artifacts are showing up for the duration of the loading new view (video attached). I tried searching the web for similar problem, but unfortunately I have not found anything browser related.

I have 2 monitors:
- Gigabyte M27Q connected via Display port
- Lenovo T2224pD connected via HDMI

The other thing that may or may not be connected to this issue is that the system starts with the second monitor (Lenovo), but when the Display port comes alive it "turns off" by going black screen and needs to be turned off and turned on to get recognised by the Windows/card. This is something that also started with the A770.

If anyone have any suggestions as to how resolve this issue, help is greatly appreciated. For now I will just browse internet with my phone.

Best regards,
Matt

I believe I have found the culprit. It was my motherboard which had firmware from 2020 and therefore was not ready for the Arc series.

I have flashed my BIOS to the newest available, enabled REBAR and now everything works as it should (the other thing with monitor not turning on also). So to all of you that might have stumbled upon similar problem, check your BIOS 🙂
