I am using Linux Mint 17.2 Cinamon. Everything is on the picture but I try to explain. When I run some linux applications windows are fully transparent. I can see only borders of those windows. There is also strange problem with icons near clock in the bottom-right corner.
For example the terminal is fully transparent and I can't use it but I know that it works because when I use the terminal from RubyMine it works. The same thing is when I start virtual terminal by Ctrl+Alt+F1.
External applications installed works fine but some apps strictly from Linux Mint got this problem. http://prntscr.com/8gqf8z
