Hi Mike,
yup, latest firmware as of just a few days ago.  2024-09-11_14-58_3.5.4_fbdec6b69a.  Please note that this has gone on through at least 1 firmware update - just wish I could remember when I first noticed it.

I know of no way to make this happen - it just does sometimes.  I'll try to be more aware of it to see if I can identify anything.
As for the second issue: the number of songs/collection name location etc. (5th screen shot) the same thing happens with the trial version on my phone (NOT e-ink version).

Optimisations are:
Display tab:
DPI setting = 350
Use original DPI = Off
Bold fonts for regular titles, menus, and body test = Off
Eliminating font aliasing = Off
Automatically full refresh when switching pages = Off

Color tab:
Add text outline = 0 (slider all the way to the left)
Background Color = 0
Image Smoothing = Off
Other Colours:
    Icon Color = 0
    Cover Color = 60
    Webpage text color = 0
    Webpage text size = 100
    Embolden Webpage Text = On

Others tab:
Stay active in background = Off
Force to follow system orientation = Off
Scroll Distance = Off
Remove Startup animation = On

I'm fairly sure most, if not all, of these are defaults.  I did adjust some things under your direction early in the piece but I don't recall what anymore - in any case I'm pretty sure those adjustments were tests and everything was restored.

I don't know if it makes any difference, but I never exit MS*, or reboot** or shut the tablet down, just close the cover to put it to sleep.

* Unless there's some odd issue and a restart of MS might fix it.
** Except when required for things like software updates.
