Button invisible when creating DVD


I want to create a DVD menu with the DVD Wizard. Everything seems fine but when I mount the generated iso and play it with vlc, the button I put on the menu is invisible. The button seems functional : if I click on the area where the button should have been visible, the title is played. I have tried different colours and different fonts, the button stays invisible.

Does anyone knows what's happening ?


More details : kdenlive 0.7.8 on KDE 4.7.1 / Kubuntu 11.04

As of 0.9.2 I am still having this occur, at least when I test it in VLC on my mac. DVD created on Ubuntu Studio 12.10 32bit

This issue is fixed in Kdenlive 0.9.4 that is available for Ubuntu from the sunab repository as recommanded on our "download" page.
