Hey @arminunruh,
I was pretty happy about finding the new overlay-feature, this is exactly what I missed before! So I immediately removed all the custom code I was using before to have a burger-menu and turned on the overlay. :-)
Unfortunately this only seems to work in Safari! In Chrome or Firefox the overlay is visible all time and destroying the rest of the content this way! (It's the same on my iPhone) :-(
Here's the link to the preview of my website. I know there is some custom code, but the problem won't disappear if i turn off all that custom code! And laytheme is of course up to date…

Hopefully you'll have a solution for this. I'd really love to launch my site soon!
Thanks and best regards!
