Qt6: mouse scrolling doesn't work after suspend until qb is restarted

[twouters]

Version info:
qutebrowser v2.5.2
Git commit: 0941c59 on makepkg (2022-12-13 09:43:08 +0100)
Backend: QtWebEngine 6.4.1, based on Chromium 102.0.5005.177 (from api)
Qt: 6.4.1 (compiled 6.4.0)

Does the bug happen if you start with --temp-basedir?: yes

Description
Mouse scrolling breaks after suspend.

Note: this is a bug in QT, I guess this report is more of an FYI. See https://bugreports.qt.io/browse/QTBUG-56214

How to reproduce
Use qutebrowser qt6-v2 branch with a bluetooth mouse or a usb mouse indirectly connected (dock / monitor / whatever) and suspend your machine. After resuming it's probably no longer possible to scroll using your mouse wheel until you restart qutebrowser with e.g. :restart.

Ah, I had that happen to me as well (mentioned in #7202), but never got around to digging into it. Great to hear it's known and hopefully getting fixed in Qt... Thanks for the pointers!

Closing this though, as it doesn't seem that there's anything qutebrowser could do about it.

Looks like there is finally a fix for this in Qt: https://codereview.qt-project.org/c/qt/qtbase/+/467903
