Hi All,
I am using QtCreator 3.0.1 installed from .bin file downloaded from Qt Project site. Recently I am having a strange issue: whenever I switch off the monitor and switch it back on the QtCreator window disappears. I can see in SystemActivities that the process is running but window has closed (I cannot see the icon in task manager either). When I run Creator from the konsole and the above issue occurs I see these errors printed:
“Qt Warning – invalid keysym: dead_actute”

I am not sure whether this is a Qt/QtCreator issue or an issue with the X11 or something related. I have also posted a question in Qt forum:http://qt-project.org/forums/viewthread/40129/
Details of my setup:
OpenSuse 13.1 KDE 4.11.25
QtCreator 3.0.1
Qt versions: 4.8 and 5.2
GCC: 4.8.1
Monitor: LG 27EA63 over HDMI.
Appreciate any help in this regard.
Thank you
