Missing buttons, options and astronauts in Kerbal Space Program
Recently, Kerbal Space Program had an update. Since that update, several buttons and options are not visible anymore.
For example, the in-game settings are not shown: 
And at the vehicle assembly, the buttons (for selecting "Engines", "Structural", "Pods"...) are invisible: 
Likewise, no astronauts can be selected, the list is just empty: 
I'm running KSP on Ubuntu 16.04. Removing all Steam/KSP files and doing a clean reinstall has not helped in any way. Do I have to wait for the next update?
Additional information: The bug disappears now in 1.1.2 (fullscreen mode and low screen resolution). Using my full screen resolution of 1366 x 768 and fullscreen, the bug re-appears.

Answer 2
This is an issue with Unity's GUI functions and the Linux Mesa drivers.
To fix it, delete your config file, and then load KSP through the launcher,and use the nearest standard resolution
To give you an incomplete list of common valid resolutions: Widescreen: 1280x720 (i.e 720p) 1920x1080 (i.e. 1080p) Narrow Screen: 1024x768 (i.e. 768ni XGA/XVGA)
Known NOT to work: 1600x900 (i.e. 900p/HD900)
There are probably more resolutions that work, and if someone knows one that does, be sure to reply to my comment with it.
