I load my clips (from my sanyo fh1 hd camcorder) and put them into the timeline. Then I add the dissolve transition and play it. Everything shows fine in the Project monitor but the part with the Dissolve transition is strange (see the attached image).
I'm using opensuse 11.2/kde4.3.5/qt4.6.2 with latest git mlt and latest svn kdenlive.
After rendering, all is fine.
