I'm experiencing a weird bug in my Forma which I think it's related to this firmware update, because I don't remember this happening with 4.37, and certainly doesn't happen with the stock version to which the firmware is reverted when a manual factory reset is performed (dated from 2020, I haven't noted down the version for that one).

I have only experienced this with books that contain insert images as well as with manga. Keep in mind that I'm talking about books from the Kobo Store, not sideloaded. Sometimes, seemingly at random, when opening one of those books, all images that the book may contain are not displayed and its space is completely blank instead. If it's a novel with insert images, the text is displayed normally but the images do not appear, and if it is a comic book, then pages can be flipped but all of them have no content, they are blank. Sometimes this can be solved by returning to the menu and reopening the book, but a lot of times the problem does not go away until the e-reader is restarted.

I can't seem to find a way to reproduce this consistently, although it also commonly happens when switching a comic book from 1 page view to horizontal spread view. In this situations, when the e-reader is rotated, images stop being displayed and even rotating it back to vertical position does not solve the problem. Furthermore, when navigating books in this glitched state, sometimes the whole screen goes completely black and the e-reader freezes, requiring a force restart.

I don't think this is about a badly formatted book, since I have seen it happen with books with which I never had a problem before. Furthermore, after a clean factory reset and further upgrade to 4.38, just downloading just one book after syncing, the problem doesn't solve, so probably isn't database corruption.

Has anybody seen this happen on their Forma or other devices? It's quite annoying.
