Libra Colour White flicker after writing notes on Kobo Libra Colour

[knghcm]

My Kobo Libra Colour shows white flicker when turing pages after I wrote some notes in the book. This usually happens at the start of the following chapter, and seems to affect some books but not others.

You can watch the video of the flicker here, where the flicker shows up after I wrote the note, and went away after I erased it: https://youtube.com/shorts/HbozvSW1uKs?feature=share

This seems to affect some books and not others, and usually happens for ePub that I side-loaded to the Kobo via Calibre. In contrast, the books that I bought directly from the Kobo store doesn't seem to have this issue.

Does anyone have the same issue for their Kobo and how did you fix it? You can also try the book out in our ereader (at your discretion of course) and let me know if you have the [snip]

Thank you very much in advance

Converting the book to kepub works to remove the white flicker: I downloaded the KoboTouchExtended from the list of available plugins in Calibre, then set the format to send books to Kobo as only kepub. It seems the plugin will automatically convert the books to kepub when sending them to the device (although you can also manually convert them to kepub via the KePub Output plugin on Calibre as well).

Plus, the highlighting and page turn is also much faster with kepub as well!
