[SOLVED] Calibre e-book viewer renders incorrectly (qt6-webengine)

When I open an epub in calibre's default e-book viewer, the text is all distorted. I'm trying to find which package caused this, I tried downgrading calibre to 7.26.0 from 8.0.1 but it had no effect. If I open the epub in another application, it renders correctly.

any ideas which package could cause this issue, or how to find out which package I can downgrade to fix it?

I think it's one of the qt6 packages. I downgraded qt6-multimedia qt6-svg and qt6-webengine to 6.8.3 from 6.9.0 and the epubs render correctly now. Should I report a bug somewhere?

edit: it's qt6-webengine

looks like it's already reported, I'll mark this solved but here's the link to the bug for posterity https://github.com/qutebrowser/qutebrowser/issues/8535

Okay this downgrade works for me making calibre ebook-viewer work again:

sudo pacman -U \
https://archive.archlinux.org/packages/q/qt6-webengine/qt6-webengine-6.8.3-1-x86_64.pkg.tar.zst \
https://archive.archlinux.org/packages/p/python-pyqt6-webengine/python-pyqt6-webengine-6.8.0-2-x86_64.pkg.tar.zst

Couple more fixes cherry-picked.

Give 6.9.0-4 pkgrel a whirl.
