Storyline 360 :: HTML5 output alignment issue

I have went through another thread reporting same issue here. 

I have tested this course on supported browser and system but still the issue is same.

Hello Parashuram,

Thanks for sharing those screenshots here. I tried replicating this behavior by adding a shape to the top of the slide in the slide master. I published the file with HTML5, and I'm not seeing a 1 pixel white line above the red header.

Would you mind sharing your file with our Support Engineers here so they can take a closer look? And be sure to let me know your case number so I can follow along, as well!

Thank you, submitted sample file to support team. Case ID is 00989126 

Thanks for sharing your case number! I can see that Angelo is doing some testing now. You should hear back from him shortly!

Hi Parashuram,

It looks like Angelo imported your project file onto a new Storyline file and the issue seems to have cleared. Please give that a try, and let us know if it works for you!

Thanks Alyssa for the update.

I tried provided solution, and it worked fine until I imported my player xml in it. After importing player, same problem re-occurred. So I tried playing with player colors, and found that Player slide background color was the issue. Setting it to 100% transparent or changing it to same color as player, solved the issue in same file. No need to import it to the another file.

The issue was in player itself.

That's so great to hear - I'm glad you got it sorted! And thank you for sharing the details of your solution, as that will surely help anyone who encounters the same issue in the future!
