QTextBrowser spews font errors

[BRut]

I've got a QTextBrowser and I set up the clickedAnchor signal to call my callback routine foo(const QUrl&).

In foo, I change the UI in various ways and the QTextBrowser will be hidden. However if I don't call its clear() method, I get errors like these:

qt.text.font.db: OpenType support missing for "", script 12
qt.text.font.db: OpenType support missing for "", script 12
qt.text.font.db: OpenType support missing for "", script 12
qt.text.font.db: OpenType support missing for "", script 12
qt.text.font.db: OpenType support missing for "", script 12

qt.text.font.db: OpenType support missing for "", script 12
qt.text.font.db: OpenType support missing for "", script 12
qt.text.font.db: OpenType support missing for "", script 12

Does anyone know why this happens? Seems like a Qt bug.

I'm using Qt 6.8.2-2 from C++.

Hi and welcome to devnet,

Can you provide a minimal compilable reproducer that shows this behavior ?
On which OS are you ?

Which distribution are you using ?
Which desktop environment ?
What about my request for a minimal buildable reproducer ?
