Seeing this too with a fresh install of Xubuntu 20.04.2 on a Ryzen Embedded V1605B
I've tested kernel 5.11, 5.12.13 and 5.13, only 5.13 was working correctly. Booting with nomodeset also corrected the display ** Attachment added: "Xubuntu 20.04.2 live CD (5.8 kernel with default options)" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1877762/+attachment/5508817/+files/IMG_20210703_202121_424.jpg -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1877762 Title: 1360x768 Vega graphics display staggered Status in Ubuntu MATE: New Status in mesa package in Ubuntu: Confirmed Status in xserver-xorg-video-amdgpu package in Ubuntu: Confirmed Bug description: This was the go-to resolution pre-update.
