I get the double flash on the home screen on boot which used to load the reading covers on 2.1.5.
I have seen that a couple of times as I have changed firmware. The first time it scared me, but I just had to do something to refresh the home page, I stopped worrying.

2. All covers on all four units now have white bars down the sides. I never get the high definition full screen covers now. Also, even though the images folder has all the required images the Library images all load slowly, one at a time all the time.

This seems to be a retrograde on the covers compared to 2.1.5, which I may revert to yet again.
For the recent firmware, the cover images for books on the SD card are generated on the fly each time they are needed. They are no longer stored in the main memory. And any cover images stored for them will be ignored.

The white bars down the side are probably because of how the images are generated. The device is using the first page of the book as the cover. That means if the cover image in the book does not fill the page, there will be empty stripes down the side. And the generation is done with the settings you use for reading the book. If you have non-zero margins set in you reader settings, these will be used. This is how it has been done for all firmware versions.

The only thing I can think of for "high definition full screen covers" is that you are using calibre to send the covers to the device. I don't think the driver sends the covers when sending the books to the SD card, but if it does, they will be ignored. I'll have to check what the driver does and fix it if needed.

I thought the SD card and cover related changes started with 2.1.4, but it might have been 2.2.0.
