I've an issue with some of the programs, packettracer among them, having a zoomed in feel to them and it is eating up screen real estate. Unfortunately I have no idea how to switch to default nor what exactly caused it.
From picture below the icons are bigger than usual, even pixelated. I maximized window to show the extent of it (close, minimize and maximize buttons are visible once mouse is hovering at the menu bar).
Here's an example of what I see:
Compared to what it should look like:
Please ignore the launcher size --- it is irrelevant to the problem.
Program in question, packettracer was downloaded from here and installed from command line. Running Ubuntu 16.04.3 LTS with 1920x1080 resolution
Any help is greatly appreciated!
