Package: libqtgui4 Version: 4:4.8.7+dfsg-5 Severity: normal Dear Maintainer,
I'm currently having some issues with running Qt4 based applications: I get a blank window when "su-ing" into another user and trying to run various Qt based applications from there. This happens for mumble, keepassx or electurm for me, for instance. GTK based applications like eog, libreoffice, iceweasel or gedit run fine from this alternative user. Usually I grant display access rights to the alternative user via "xhost +local:linus". However "sudo gksu -u linus mumble", too, just gives me blank windows. The X server runs within a VNC session, started by Xtightvnc. The window manager within that X server is Xmonad. Running Qt4 based applications via ssh X forwarding instead of VNC works fine though. At least after granting the user "linus" read/write access to ~/.Xauthority of the user that started lightdm/Xtightvnc/Xmonad/... and setting a symlink from /home/linus/.Xauthority to /home/$x-server-owner/.Xauthority.
