Wrong window dimensions

[tmolitor-stud-tu]

When the history of our filter input contains a very long query, the window will enlarge beyond the bounds of the screen, even if already in maximized mode.

Sometimes you need to filter and/or clear the filter again to trigger this bug.

This seems to be a QT problem... I'm not sure if this can be fixed without changing the entire combobox code! (→ like shortening the str manual to the specified character length)
