White line around player and Master layer banner

I'm I the only one seeing this? Using a 4K monitor Storyline 360. I've gone through the entire css via F12 on Chrome Developer and turning off each item one at time did nothing to resolve this. Using classic player, Chromeless colors on Black Background. ALL BORDERS are set to Black !!! 

I guess I'll have to post every day to get to top of forum and see if anyone can resolve this.

I guess I'll have to post every HOUR to get to top of forum and see if anyone can resolve this.

added the following to F12 Chrome developer's css panel

* {
-webkit-backface-visibility: hidden;
transform-style: preserve-3d;
}

It took the white line away. However, I'm not going to screw with the CSS. Can someone send the Storyline developers this. Have no idea why no one replies to my posts. Please FIX this issue on Windows 10 using a 4K monitor and Windows scaling.

I'll assume this will never be fixed as usual.

Hi Ken!

Sorry, you're still running into this bug! We did release a fix for the white line around the Player, and I do not see this behavior in Storyline 360 Build 3.42.22792.0.

Here are screenshots where I've added a black background and used both the Modern Player and Classic Player:
