Launcher starts with default size then jumps to configured one on login

[Roman Yepishev]

STR:

1. Set launcher size to 32px in System Settings / Appearance
2. Log out
3. Log in

Expected results:
When launcher appears, it is 32px wide.

Actual results:
Launcher appears at full size (64px?) then switches to the configured width after a little while.

Thank you for reporting this bug. I can confirm this here.

The cause is launcher is created and gets drawn before the icon size is set (though the CCSM options). The fix would most likely be in unity/plugin/unityshell/src/unityshell.cpp (its a huge file). Looks for launcher_controller_ (line ~3216) and where it gets created (with an std::make_shared). You will most likely have to change the launcher_options_ icon size right away vs waiting for it to get set. Right after this we should most likely try and set the icon size from compiz. We currently are setting it here:
 case UnityshellOptions::IconSize: (about line ~3039).

Hopefully this gives enough info to help get started :).
