[ubuntu] Android studio title is invisible on the title bar when maximized.

I use android studio on Ubuntu because is a lot faster than windows among other things. However I have an aoying problem.

When android studio is maximized the title disappears, photo 1.
When the app isn't maximized the title is shown perfectly, photo 2.
Another case is when android studio is maximized but without focus, then the text is shown.
