Hello,
I am using Mantra as the theme for http://abaptechs.com/ and I experience a bug in responsiveness when the window size width is between ~40% to 99% od the screen, in a 1080p resolution. When the width is small (and the sidebar disappears) the theme goes back into responsive mode. For 720p resolution this is even worse, as a huge scrollbar appears in the botton. Again, when the window is small and the sidebar disappears, it starts wordwrapping and resizing images again.
I tried disabling all plugins and the bug persisted even with an empty sidebar.
My layout configuration is: 2 columns, sidebar on the left; Dimensions “Absolute”, content = 1510px; sidebar = 340px; Responsiveness enabled.
Thank you!
