I was having the issue also when the charger was not connected. The fix was to turn the brightness down. The issue only occurred at full brightness and if I brought the brightness down while it was happening I could watch the problem stop in real time. Normally leave the brightness at the mid-level, but have had promising results with the adaptive brightness setting too. Going on 2 months without having to deal with the issue, and it had been an everyday problem.
