I am facing this issue with Ubuntu's top bar that every time when I restart or boot up my PC the icons from top bar will become smaller and then I need to got to Universal Access and turn the large text on. I have tried every possible internet things but nothing works and I filed to find the problem.
Here is the image of smaller icons.
Can anyone suggest better solution?

I seen two work arounds in these threads that you can try. Or wait for bug fix.
Downgrade libmutter:

Create script and run each starup:
For this one, please notice you rather like scale up and not down.
