Every QT-app on Ubuntu is not rendering and throwing an excessive amount of "Painter not active" warning -


the title kind of says all. i'm running ubuntu 14.04 server , started fresh install added desktop interface , nvidia's cuda toolkit , driver (without overwriting opengl libs).

what happens following:

  1. i open application relies on qt interface (this includes qt creator, ironically).
  2. a window opens whole window filled displayed @ time of popping behind window.

  3. i hover mouse on icons supposed induces ton of warnings in following format:

    [8171] warning: qpainter::devicetransform: painter not active [8171] warning: qpainter::worldtransform: painter not active [8171] warning: qpainter::pen: painter not active [8171] warning: qpainter::setpen: painter not active [8171] warning: qpainter::setpen: painter not active [8614] warning: qwidget::paintengine: should no longer called [8614] warning: qpainter::begin: paint device returned engine == 0, type: 1 [8614] warning: qpainter::devicetransform: painter not active [8614] warning: qpainter::worldtransform: painter not active

  4. nothing else happens. when window dragged along lines of

    sigsev in qdrawborderpixmap

    might crash app.

i'm sure there wrong system package rather individual applications, case error. i'm not sure start repair process, ideas welcome.
