Dear Lakshminarayana, dear Chris, dear Jani,
thanks for opening this bug, but it seems nothing to happen with that.
Can I do anything to trigger this and bring that back to focus. It is an
really annoying bug and this flickering screen drives me crazy and with
"intel_idle.max_cstate=4" runtime is dramatically reduced.
From what I read maybe you Chris have biggest knowledge. Can you give
me some feedback? Shall I give up hope?
Best regards,
Arno
