Comment 16 for bug 1768264

The line in question was introduced by rev1672, or probably 1637.1.4 more specifically. "Fix the colours to use public ones, and make Adwaita hover fix consistent." from 2016-12-08.

             .terminator-terminal-window {
- background-color: rgba(0,0,0,0); }
+ background-color: alpha(@theme_bg_color,0); }

I'm curious why it added alpha(...) when the patch didn't do that for other window elements, e.g.:

             .pane-separator {
- background-color: @bg_color; }
+ background-color: @theme_bg_color; }

I notice if instead of changing it to white, I just change it to the theme_bg_color it looks great. I.e., change the sed line from the test case in my previous comment to:

$ sed -i 's/background-color: alpha(@theme_bg_color,0); }/background-color: @theme_bg_color; }/' /usr/share/terminator/terminatorlib/terminator.py

I think removing the "alpha(...)" is the right fix for this bug, unless anyone knows different?
