EDITED
The problem is not with OmniBar. I solved this turning Masque off for OmniBar. Probably some kind of conflict...

All good now! TY

Hi! First of all, tks for your work. Omnibar is as natural to WoW as player frames.

My issue is with the Swipe Transparency slider. Just doesn't do anything. Stting it to 0% or 100% makes no changes at all...

Thank you!
