Hi, FreeCAD also has some issues with the rendering of its "start page" where the text is missing. And as Calibre and FreeCAD are apparently both Python applications using QtWebEngine, it may indicate that there is something not working correctly in QtWebEngine or in the Python bindings to

It's not easy (perhaps impossible) to bisect the core-updates branch. That's because most commits on the branch are not expected to build. For most of the branch's lifetime, it's merely a place to dump patches that cause rebuilds of the entire distro (e.g. a glibc update). It's only in the

My description of the bug was hasty. The viewer is still broken in the same way, but I realize now that the text is not invisible or unselectable. Rather, selection still works but only displays selection markers at the upper left corner of the screen. According to a bug report about Calibre,

After looking into what I think was core-updates(-frozen), I am running into a wall in the form of glib-networking, which blocks my attempts to build Calibre on many commits. However, I did find another merge which may be of interest: b029be2ee0f81cdcbc14240ff426408085ab0a40. One side of it,

The substitutes to install Calibre 5.36 updated, so I gave it a try today. The issue exists there too, suggesting further that the problem is in the dependencies somewhere. I haven't come across a working revision with Calibre 5.14 in my bisecting expeditions yet, but I suspect some of those would

I realize that the conversation has been continuing outside the bug tracker. 9d25ee30b188f9202cc14f7cd25ba8a1c3ec1a72 has a working version of Calibre 5.21.0. 6dffced09ecda024e0884e352778c221ad066fd6 is the commit where it broke. That's a big merge commit, and Calibre is only broken in one of the

Calibre's main window is unaffected, but it's impossible to read any EPUBs in the viewer. The text in both the book and the settings is affected. Images show up. I don't remember if I noticed this before or after the bit QtWebKit removal a few weeks ago. It would be a strange root cause but is
