Which devices is the best for that?

I have tested different desktops, window managers, OS and kernels, but the problem persists. The problem: When I move a window on the desktop, the cursor icon flicks. If I use no GPU driver (LLVMpipe), no problem! Tested on; SBC: Odroid-C4 OS: Focal, Buster and Hirsute Desktop: Xfce, Mate, Gnome, LXQT Window Manager: OpenBox, Mutter, Xfwm4, Metaccity Panfrost: 21.0 and 21.0.rc5

I suspect the problem is related the hdmi-hotplug script. After some testing, I found out the /usr/local/bin/hdmi-hotplug in my C4 is targeted to card0, but in my case sometimes it is card1 or card0. This is probably caused by using the same monitor for the C4 and my home computer.

Yes, I tested with buster and it works ... same kernel!

The GPU accelerated trend with the SBC community will depend on the Panfrost driver development. After some testing on current version of Mesa (20.2.6) on Armbian, only the Midgard series (Mali-T###) will work. Mali-G30, Mali-G50 and Mali-G70 series (Bifrost) is not included in Mesa (20.2.6) without tweeking. At the current time the Mesa project version 21.1, the Panfrost driver is unstable/broken and several commits behind the target branch (master). Might be worth waiting until the official release is available!

It WORKS, :-)

Tested this morning! I tried with other OS with the same methode direct on my USB EMMC Module Writer attached to my Ubuntu computer. ubuntu-20.04-4.9-minimal-odroid-c4-hc4-20201212: OK DietPi_OdroidC4-ARMv8-Buster: OK CoreELEC-Amlogic-ng.arm-9.2.5-Odroid_C4: OK selfinstall-odroidc4-49-64bit-20210108: OK Manjaro ARM 20.12: OK ArchLinuxARM Image Generator: Fail Armbian_20.11.10_Odroidc4_focal_current_5.9.14: Fail

I tried Armbian_21.02.0-trunk.80_Odroidc4_focal_current_5.10.10_xfce_desktop and it is not booting, same problem.

Image used Armbian_20.11.10_Odroidc4_focal_current_5.9.14_desktop.img It works with micro SD (eMMc not inserted) Not booting with eMMc (SD not inserted), With SD & eMMC, system boot from SD .. . I tried nand-sata-install -> "Update bootloader" script same problem. see the attached output error from my monitor

Unfortunately ChromeOS image no longer provides 64bit components ... try to install the 32bit version of Vivaldi and follow the ARMv7 instructions. (widevine is listed on vivaldi's componets as Widevine Content Decryption Module with version 0.0.0.0, is this right?) this is normal!
