True that. It was rather cool to see the line slowly crawl upwards, leaving everything under it frozen.
It seems to have stabilized, though! It's been like the attached img for a few hundred page turns so far.
I made sure to set the viewport a couple pixels
above the unusable area. My thinking being avoiding asking the device to update that part of the screen.
Even though replacing it wouldn't be expensive, I think it was worth the trouble if we can squeeze a few more books out of it as a secondary ereader.
I'll edit this post if it gets any more borked
