Steps to reproduce:
1. Upload recording
2. Copy embed code
3. Embed to blog (here: Blogspot)
Timeline is "broken" horizontally (white-black-white); cf. screenshot for IE
Timeline should be white (cf. screnshot for Chrome)
Workaround (if any):
Could you have a look at it? I don't want to set up Matterhorn on Windows, not to mention Windows itself...
Embed player timeline not broken anymore, but partially covered by the lower bars. Cf. attachment.
