Ok. So it is strange that the opacity does not work when you change it through the annotation toolbar. You should check/post your ~/.config/okularpartrc because there you can see the actual value of the opacity. Once you change the opacity and close Okular the value gets written in the file. Looking at that file may help in figuring out why the opacity is not set correctly for you.

I cannot reproduce this. Does this happen for all the annotations? Can you set the opacity of a tool to 90%, close Okular and then post the content of ./config/okularpartrc? Have you tried to reproduce this in the current version of Okular?

Haven't tried it in the current version, gonna do that tomorrow.
