[Qgis-developer] Print composer: problems with thin arrow lines

[Andreas Neumann]

 Hi,

 In many layouts I use thin lines (e.g. as divider lines). Mostly they 
 are vertically or horizontally. For some reasons these lines are not 
 visible when in page zoom, but appear if I zoom in to the layout. 
 Usually they have a line-width of 0.2mm. If I increase the line-width 
 these lines get visible.

 This is purely a preview problem. When printing or exporting these 
 lines are exported or printed properly.

 Is this a qt rendering problem of thin lines? Is there some setting 
 that would make sure these thin lines are always visible?

 Thanks,
 Andreas
