Hadn't noticed this myself, I'll try it to see if mine does it.
There is an auto-brightness issue I found a way around that might be worth mentioning here. On mine the auto brightness was so severe, dimming all the way down in even well lit rooms, I couldn't use it. I found a cure by switching on the "outdoor" mode of Super IPS+. When doing this the auto brightness works acceptably well, like my old TF101 does.
