Public bug reported:
After each brightness-step change (via using Fn+arrow up-/arrow-down
keys), system freezes for ~500ms. With my notebook's 10 brightness-
levels, this often results in total delay from 10x 500ms, = 5 entire
seconds for the notebook finishing a multi-step brightness-change in
very very laggy steps, when the user input already stops within 1-2
seconds.
Also, the brightness update-rate symbology is often freezing entirely
for up to 5 seconds before indicating that brightness was changed at all
(see screenshot in comment #2 for symbology)
