Issue with latest QScintilla

[Detlev Offenbach]

Hi again,

today I retested the situation on Ubuntu 22.04 and was able to reproduce 
it with PyQt 6.3. However, it did not always occur on the first attempt. 
Most times you had to move the cursor around to various positions and 
eventually eric7 crashed when trying to show a completion list.

Using the PyQt 6.4 snapshot I could not reproduce it. The completion 
lists were shown without a crash. Maybe Qt 6.4 improved the Wayland 
handling and the observed issue is really a Qt rather than a 
PyQt/QScintilla issue.

Regards,
Detlev
