Hey,
This bug has been around for a while (I think after the WordPress 4.0 update) but I left it thinking it would be solved in future versions… but not the case so far.
The issue is that when you transition from the swift page builder to the WordPress classic editor there is a couple of display/css bugs.
Bug #1. First click on the classic editor – huge whitespace created above the code. Only corrected by scrolling down the page
Bug #2. Secondary click on the classic editor – lots of css issues. Again it corrects itself when you scroll down the page.
Best illustrated in the short screen-cast in the next post.
Thanks.
