An update on current stability problems - was: Re: Problem installing in Windows

[Thomas Friedrichsmeier]

Hi,

a short update on my thoughts/plans to address current - QWebEngine-related -
stability problems, as this may actually take some time to implement:

1. It feels like 90% of our issues stem from QWebEngine, of late. And this is
not even counting problems WRT building and packaging.

2. QWebEngine 6.10.1 - which is currently in use on our builders - appears to
be a particularly buggy version. Qt 6.10.2 is out, and there is some hope that
it will resolve some of the issues, but I cannot give you a timeline on just
when it will be available for our builders (hopefully within a week or two),
nor a promise that it will actually help.

3. Even if QWebEngine 6.10.2 does solve the current problems, I'd love to have
some alternatives. Yesterday I learned that Qt's other web component (QWebView)
has meanwhile learned to use system native HTML viewers on both Mac and Windows.
That sounds like it may avoid a whole class of troubles at least on those
platforms. QWebView is not going to be quite trivial to use, however, as the
coupling is much more indirect, and we will have to somehow add support certain
functionality (importantly handling rkward:// and help:// urls) via injected
javascript, and - probably - websockets. I'll experiment in that area, next,
hoping this will turn out to be a viable solution.

4. In the longer term, I hope Servo will bring back some diversity into the
embeddable HTML render landscape. But that does not look like a solution for
2026, yet.

Regards
Thomas
