Description Peter Hostačný 2015-10-08 11:28:36 UTC

Description of problem:
When I try to launch dolphin under root, I get asked for password as normal, then the window shows, but the main pain is just blank/gray. I am using F22 with gnome desktop environment, so maybe it is issue related only for gnome users.

Version-Release number of selected component (if applicable):
Using: GNOME Shell 3.16.3
Qt: 4.8.6
KDE: 4.14.11
Dolphin: 15.04.0

How reproducible:
always

Steps to Reproduce:
1. $ sudo dolphin
or
1. $ su
2. $ dolphin

Actual results:
gray window

Expected results:
normal window displaying dolphin GUI

Workaround:
"QT_GRAPHICSSYSTEM=raster [kdesu|sudo] dolphin"
"QT_GRAPHICSSYSTEM=native [kdesu|sudo] dolphin"

It's more than just similar, it's the same one.

The workaround is the same, to run qt4 apps as root, set environment variable,

QT_GRAPHICSSYSTEM=native
