A very good day to you.
I noticed a problem with Web Remote (0.9.7) in OpenLP (2.9.5).
When I switch to show black, the view under main does not go completely dark (screenshot: 1 normal → 2 show black).
In addition, when I click on show black again, the view does not become completely bright again (screenshot: 3 show black 2nd click).
Only switching to the next verse solves this problem (screenshot: 4 switch to next verse).
