And that's what made me decide to return the Libra and get an Oasis 3.

But as lots of people have mentioned in the Kobo Libra thread, no one else seems to have this same problem with the Libra. So it could all be in my head. But to me it's very noticable and when comparing the Libra with either the Voyage or the Oasis it puzzles me that no one else seems to notice this difference.
One possible reason is that some Kobo devices (not sure about the Libra) use Pulse Width Modulation (PWM) as a way to control brightness; the LEDs are rapidly switched on and off, and the ratio of time they spend in the on state vs the off state determines the effective brightness. Some people are more sensitive than others to this flickering. Kindles don’t use PWM to control brightness.
