In case anyone’s still interested, I can confirm this is not only an issue with RAWs from my Fujifilm X-T4.
Just had a go with this one that was taken with a Huawei phone and can observe the same happening.
Though I’m noticing, toggling the left or the bottom panel ot the UI also toggles the bug. Not something I noticed with my RAWs, but I might just have not messed with the UI this much in the past
