after pressing F11 the game flashes twice and minimize to tray, clicking on it to restore the window just leave it minimized
The only way to get the game window back is to press F11 just immediately after clicking on the minimized icon or to adjust the options.txt
It is impossible to play the game in full screen!
The bug is (now) also in earlier versions (1.7.10) - perhaps from an updated java library?

After reading the issue links I examined my Minecraft environment.
This is a short description of the appearance of the bug:
1) Using Minecraft launcher with Java 8.50 and AMD driver 14.12 -> no problems
2) Updating AMD driver to 15.7.1 lead to my bug report (which I recognized not immediately, because I didn't played Minecraft at the time of the update)
3) Updating to Java 8 Update 60 (x64) helped, but why?
The Minecraft launcher log (still) says "ystem.getProperty('java.version') == '1.8.0_25'"
I always used my "game link" which leads to "C:\Program Files (x86)\Minecraft\MinecraftLauncher.exe". And there is only a runtime java 1.8.0_25 in it... - I'm totally confused.
Even F3 in game says 1.8.0_25 (see attached screenshot)
UPDATE: After upgrading to Java 8.60 it works (Java 8.50 was installed)
