I can also confirm the bug on Ubuntu 14.10 on ASUS UX303LAB.

$ sudo dmidecode -s bios-version
UX303LAB.205
$ uname -a
Linux UX303 3.16.0-33-generic #44-Ubuntu SMP Thu Mar 12 12:19:35 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

A possible workaround:

I have screen brightness control through the system settings, but not
through the Fn+F-keys. This works if acpi_osi=intel is in the boot
parameters, or there is no "acpi_osi" mentioned. For example, only
"quiet splash". If you install xbacklight from the Ubuntu repositories,
the commands

$ xbacklight -dec 12.5
$ xbacklight -inc 12.5

decrease and increase (respectively) the screen brightness by 12.5% (I
picked 1/8th total, but another choice will do). So, in keyboard
settings I mapped these commands to Alt+F5 and Alt+F6, which seems ok so
far. Hopefully this will make things easier until a fix comes out.
