I`ve a question and I`m not sure if I`m encountering a bug or doing something wrong. I just played around with designing custom themes and I`m now ready so far.
If I now choose my theme or any other and I switch to "Widgets" Tab, there I can add widgets to placeholders or controllers ... okay so far.
If I do so, then on the next screen I get the option to change the widget symbol. When I now choose a PNG with transparency, the transparency will be ignored and I get a ugly background colour behind my icon.
I`m using Web AppBuilder 2.2 and here`s what I found in my build_num.txt (maybe it helps you)
Can someone reproduce this behaviour?
