Running Coreelec 9.0.1 9.0.2 or Nightly june 9th, I experienced regular black screen blinking not only when viewing video but also in GUI.
It looks random, but when it starts blinking (random frequency) it stops only after reboot.
For example, I have watched TV and after 3 hours the screen started to blink. I have restarted and up to now it works.
What can I do to troubleshoot ???
my kodi log is there http://dl.free.fr/mFZe0BvOB
Thanks for your help
