Title:
OpenGL windows always on top with Unity-2D and fglrx driver
Status in unity-2d:
Invalid
Status in unity-2d package in Ubuntu:
Invalid
Bug description:
When running an OpenGL application with Unity-2D (3.8.4.1) there is visual
corruption in certain situations. So far I identified the following problems:
- if the launcher covers any part of the OpenGL application's window, it
will flicker when appearing and disappearing and may even become totally
invisible (behind the OpenGL window?)
- dragging a non-maximized OpenGL application's window will cause severe
flicker inside the application itself
My system is Ubuntu 11.04 using the latest 11.6 version of fglrx and I
still haven't tried with the free Radeon driver. Will report back as
soon as I test that. There is no corruption when using normal Unity.
Steps to reproduce:
1) open an application that makes use of OpenGL acceleration and can run in
windowed mode (e.g. glxgears, blender)
2) make sure that the application's window can be covered by the unity
launcher
3) move the mouse to the top left side of the screen so the launcher appears
Expected results:
There is no corruption in the areas where the launcher intercepts the
application's window
Actual results
Visual corruption in the areas where the launcher intercepts the
application's window
