QComboBox don't get Qt::Key_Return on XRDP

Hello,

I have a problem with QComboBox and XRDP on a Linux host. I want to select an item from the QComboBox with my keyboard.

If I logged in with XRDP I can't select an item from a QComboBox with the enter- or return-key from my keyboard.

If I logged in directly to the linux machine I can select items from a QComboBox with the keyboard. So everything works fine.

It looks like the KeyRelease-event won't go to the QComboBox. It seams that the KeyRelease-event stuck at the QComboBoxListView.

See the traces below:

XRDP connection:

object= QComboBoxListView(0x80fe968) event= QEvent::Type(KeyPress)
key= 16777220
object= QComboBoxListView(0x80fe968) event= QEvent::Type(KeyRelease)
key= 16777220

Linux machine directly:

object= QComboBoxListView(0x8af6560) event= QEvent::Type(KeyPress)
key= 16777220
object= QComboBox(0x8a808b8) event= QEvent::Type(KeyRelease)
key= 16777220

Any ideas how I can avoid that?
