Comment # 12 on bug 1044727 from Stanislav Brabec

I found an easy way to reproduce on any HDMI display that supports multiple
modes.

#based on cvt 1280 800 75
xrandr --newmode "1280x800"  106.50  1280 1360 1488 1696  800 803 809 838
-hsync +vsync
xrandr --addmode HDMI-1 1280x800
xrandr --output HDMI-1 --mode 1280x800

Now the monitor runs in resolution 1282x800

I experimented with more resolutions, and found that the error does not happen
in the most basic modes (1360x768, 1024x768, 600x400, 1920x1080), but happens
in a less standard modes (e. g. 1280x800, 1920x1200). It seems that it happens
in modes listed in hdmi_group=2
https://www.raspberrypi.org/documentation/configuration/config-txt/video.md,
but it could be just a random coincidence.


I am still failing to install and test Tumbleweed (new u-boot does not support
my USB keyboard and ends with a prompt, old u-boot does not support it as well,
but it can boot installation DVD image without prompt, but the boot stops to
display anything after writing "starting udev". And finally, XFCE appliance
image fails on write error while unpacking initrd (out of memory?)). My
hardware is Raspberry Pi 3.
