Upgraded Calibre to 7.8 (on the same AMD Adrenalin version as before 23.12.1) and getting this ebook viewer rendering issue once more.
Window shows up but only renders white when maximized or in windowed mode but larger than the screen / out of bounds. If the window Mouse pointer changes when over different elements and text can be copied, but only renders as white.
Ebook contents only visible if launched with the window strictly smaller than the size of the screen in windowed mode. Text is not rendered properly and needs to be dragged against the top of the screen (some kind of pre-maximization step?) and then dragged backed down to not render it as white. Once it gets rendered white it won't change back and needs to be relaunched.
Here's the output when running from the command line:

EDIT:
Back to working maximized after a restart. Still requires window to be dragged and "bumped" against the top to fix font aliasing though.
