The display is physically mounted in portrait mode (9:16), so I need to rotate the output 270°. When rotation is applied, a visible vertical line artifact appears running from top to bottom, approximately 5cm from the right edge of the screen. Without rotation, the image is perfectly clean — no artifacts at all. What I've tried (all failed to fix the issue): CSS rotation (current method): Using transform: rotate(270deg) on the body element. The line artifact appears consistently. xrandr rotation: xrandr --output HDMI-1 --rotate left — same vertical line artifact appears. Kernel DRM rotation: Added video=HDMI-A-1:1920x1080@60,rotate=270 to kernel cmdline in extlinux.conf. Parameter is visible in /proc/cmdline but has no effect — Rockchip DRM driver does not support the rotate parameter. Chromium flags (tested individually and in combinations): --disable-gpu-compositing — moved the line to the center of the screen --disable-gpu-rasterization / --disable-gpu-vsync — made it worse --use-gl=egl — no effect --enable-gpu-rasterization --enable-zero-copy — no effect --default-tile-width=1920 --default-tile-height=1080 — no effect --gpu-rasterization-msaa-sample-count=0 — no effect --force-device-scale-factor=1 — no effect --use-gl=angle --use-angle=gles-egl --use-cmd-decoder=passthrough — crashed Chromium CSS GPU optimization properties: Tested translateZ(0), backface-visibility: hidden, will-change: transform on the rotation container — no effect on the artifact. Chromium 132 upgrade: Installed chromium 132.0.6834.159-1~deb12u1+rkmpp from liujianfeng1994/chromium PPA. The vertical line remained, and video playback became unstable (freezing). Reverted to Chromium 114. Mesa upgrade to Ubuntu noble-updates 25.2.8: Removed Panfork PPA and installed standard Ubuntu Mesa 25.2.8. GPU fell back to llvmpipe (software rendering) — no Panfrost support for Mali-G610 in standard Mesa. Display showed tearing in the center. Reverted to Panfork 23.0.5. Conclusion: The artifact appears with any rotation method (CSS, xrandr, kernel) and persists across Chromium versions and various GPU flags. This strongly suggests the issue is in the Panfork Mesa / Panfrost compositing layer when handling rotated output on Mali-G610. Has anyone encountered this issue? Is there a known fix or workaround? Would upgrading to Panthor (with kernel 6.10+ or the 6.1 backport) potentially resolve this? Any help would be greatly appreciated.

Hello everyone I wanted to build Armbian on the AIO-3588Q board. But I did not see that there was a configuration of this board. There was a configuration of the ITX-3588j board and other manufacturers on the same rk3588 platform and tried to build Armbian. In the assembled images in GPT format, only rootfs was stored (it combines rootfs and kernel (boot.img) according to the rockchip documentation). After I built it, I installed it in the rootds partition, it was installed without any errors. But the system does not start. You turn on the power, the fan starts spinning very fast, spins for 5 seconds, the lower LED lights up, and then the fan stops, the light goes out, a second passes and the fan starts spinning again. I tried to get logs through the debug port, nothing was output except Chinese characters mixed with question marks (binary data) I tried to create a custom board profile for building Armbian, but I constantly got errors during the build. Dragged all dts and makefile from source firefly. Also could not understand what is needed to modify uboot so that uboot can run from gpt kernel located in rootfs. Please tell me how to: 1) Get logs from uboot and connect to its command line? 2) How can I build Armbian for AIO-3588Q together with Uboot? Or build Uboot separately, but what is needed for correct parsing of GPT from rootfs? Maybe someone had experience of building for this board
