Status in linux-raspi package in Ubuntu: Triaged Status in linux-raspi source package in Hirsute: Triaged Bug description: - System: Raspberry Pi 4 Model B Rev 1.4 - O.S. Ubuntu 21.04 Desktop Beta arm64 - Kernel: Linux fpgrpi 5.11.0-1005-raspi #5-Ubuntu SMP PREEMPT Fri Apr 9 13:10:37 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux - Package version: linux-raspi 5.11.0.1005.3 - Desktop: GNOME 3.38.4 tk: GTK 3.24.25 wm: gnome-shell dm: GDM3 3.38.2.1 Distro: Ubuntu 21.04 (Hirsute Hippo) - Display: server: X.Org 1.20.10 compositor: gnome-shell driver: loaded: modesetting unloaded: fbdev display ID: :1 - OpenGL: renderer: V3D 4.2 v: 2.1 Mesa 21.0.1 direct render: Yes Problem summary: ---------------- Most of times, after boot, the desktop is shifted 1 pixel to the right when attached to an HDMI monitor. It means that the most right vertical line is shown at the left of the screen. It only happens using the full kms drivers vc4-kms-v3d and vc4-kms- v3d-pi4, and not always but most of times. It doesn't happen using the fake kms driver vc4-fkms-v3d. I'm using X.Org, not Wayland. I've checked dmesg and journalctl messages and didn't found any related error. I also tried a fresh install of Ubuntu 21.04 Beta and got the same problem.
