Ubuntu – Graphic driver Linux kernel 5.3 problem Ubuntu 19.10 AMD Ryzen


I have problems probably with graphic drivers. I attach my screen. During using GNOME desktop and Firefox, I see blurred picture, but not all time only sometime.

When I used Ubuntu 19.04 everything was OK. I saw the same problem with Fedora and kernel 5.2.
Windows 10 works OK.

I have Huawei MateBook 14D with AMD Ryzen 2500U.

I coped amdgpu firmware as is described in https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-19.10-Radeon-RX-5700 and added Oibaf PPA and Ubuntu works OK.
