When using the Qt Virtual Keyboard qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard")); in combination with the Material Style, there are overlay and event propagation issues with dialogs.
 
Issue 1 – Dialog not closing on outside click

• In the small-sized dialog view: clicking underneath the dialog does not close it.
• In the maximized dialog view: clicking to the left or right of the dialog also does not close it.
• This behavior occurs only when the virtual keyboard is enabled via the above qputenv setting.

 
Issue 2 – Events passing through an open dialog

• When a dialog is open, click or touch events are incorrectly passed to elements behind the dialog.
• This allows interaction with underlying UI components while the dialog is visible, e.g.:
  • Typing into a TextField using the virtual keyboard.
  • Moving a slider.

 
Platforms affected:

• Windows 10 – tested from Qt Creator 17.0.0 using Qt 6.8.4
• Ubuntu 24.04 – tested from from Qt Creator 16.0.2 and a standalone application using Qt 6.8.3

 
Expected behavior:

• Clicking outside the dialog should close it.
• While a dialog is open, underlying UI elements should not receive input events.
