Public bug reported:
Operating System: Xubuntu 14.04 (Update from 13.10)
CPU: Intel Celeron 847 1,1GHz
RAM: 4GB
Graphics: Intel HD Graphics 2000
Steps to reproduce the issue:
- Open multiple windows on seperate workspaces.
- Switch between windows via Alt+Tab.
Expected Result: Application windows are rendered correctly, there are no
visible graphical glitches.
Actual Result: There are graphical glithes where the active window is only
rendered partially, e.g. switching from Thunderbird to Chromium leads to a
mixture of both applications. When hovering the mouse pointer over elements,
those are updated and rendered correctly. The same effect may happen when
minimizing / maximizing windows.
Workaraound: Instead of using SNA, fall back to UXA rendering mode.
** Affects: pidgin (Ubuntu)
