Description Yichao Yu 2013-10-15 15:25:04 UTC
I'm not really sure if this the right place for this since this issue affects all (released) qt4 styles which supports translucency (AFAIK, QtCurve, Oxygen-Transparent, Bespin) and what I have found is just a workaround.

The problem seems to be that there is a QGLWidget (Analyser::Base2D) in the amarok that when not being set to TranslucentBackground while other's ones are crashes in mesa on drawing. However, a simple program with a QGLWidget does not have the same problem so I'm still not sure yet what exactly is the cause of this.

I am not really familiar with OpenGL but I think this is probably a good start for fixing this problem (and this is why I report this issue here). The workaround I am using now can be found here[1], which is setting background translucency for all QGLWidget and I haven't found any regression after doing this yet.

Screenshot of the widget which causes the problem (top part, not sure what it is called...) as well as a translucent amarok with that widget.
