I would like to change the transparency of tooltips to make them more readable, but I cannot find the correct file and setting. Here is an example of the problem:
The colors will change if switch to another LXQt theme, but the transparency persists. At first I thought I could edit the themes in /usr/share/lxqt/themes, but none of the files seem to contain what I’m looking for (I don’t know the setting name so I may have overlooked it).
Thanks humpty, Compton was the problem! Turning it off removed the transparency. I guess I’ll have to install some kind of Compton settings manager before I turn it on again.
