Description Martin Klapetek 2013-11-09 09:23:53 UTC 
Xorg-server/Xephyr version: 1.13.4
Distro: Kubuntu 13.04

When trying to run any Qt5 (or apparently GTK3) apps inside Xephyr, they don't work (as in nothing is shown). GTK2 or Qt4 works just fine as well as GLX apps (glxgears for example). Also tested on standalone X server with no DM running - Qt5 works perfectly fine there, just inside Xephyr they don't.

I've also heard that once any wm is run inside Xephyr, all apps work then, but I didn't test that and can't verify atm.

Might also be a Qt5 bug, but given there are reports[1] that GTK3 doesn't work either, I report a bug here.

I'm happy to provide any testing/info you need.

Oh I should mention my Qt is self-compiled 5.2~git30102013
