Comment 5 for bug 146101

Checked the issu in latest image on Q1 ultra, Virtual keyboard works well for applications mentioned here: xvncviewer, xtightvncviewer, chimera2 (a Web browser), and axe.
Press F11 in real keyboard to fullscreen, no issues happended on xvncviewer and xtightvncviewer. So I think the issue has been fixed.
But when launch xvncviewer and xtightvncviewer in terminal, the pop-up menu doesn't has title, is it possible to push the minor issue fixed?
