Crash when interacting with <select> when having more than a single open tab

[Lilith-In-Starlight]

Version info:
qutebrowser v2.5.2
Git commit: f911ffd on v2.5.x (2022-06-22 16:04:52 +0200)
Backend: QtWebEngine 5.15.2, based on Chromium 83.0.4103.122
Qt: 5.15.2

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

Description
When interacting with a select html element (one of those lists that you click to expand it into multiple options of which you can only choose one), qutebrowser will crash if (and only if) there are more than one open tabs.

How to reproduce

Open qutebrowser

• Open https://pandoc.org/try/ (or any page with select elements) in a new tab. The link can be any page, I just use that one for testing because it's relatively quick to test the issue in
• Interact with the select elements. In the page I provided, these elements would be the "from" and the "to" fields
• Qutebrowser will freeze. On windows, a black square appears where the list of options would be, and then qutebrowser crashes.

I cannot reproduce, and this is the first time I'm seeing this reported I believe.

A few questions:

• Could you share your full :version information please?
• Can you try another browser using Qt 5 with QtWebEngine, such as KDE Falkon?
• What graphics hardware / driver is this on?
• Any chance you could try the qt6-v2 branch? See Switching to Qt 6 by default #7202 for details.

This crash didn't happen in Falkon
Will attempt to try that branch

Closing due to inactivity, and this is likely an issue with Qt and/or your setup. Let me know in case you can still reproduce with Qt 6.
