I've just recently updated to Gnome 3.14 and openSUSE 13.2 from Gnome 3.12 on openSUSE 13.1 (using an additional repository). I play a game called Revenge of the Titans, which appears to use LWJGL. Since the upgrade, running the game in full-screen results in it being positioned about 100px down and 100px to the right, so I can see a strip of the top and left of my desktop and I lose the bottom and right of my game.
I've also tried the fullscreen demo (
http://www.lwjgl.org/webstart/demo.php/test.opengl.FullScreenWindowedTest) and that also exhibits the same behaviour. I've attached a screenshot.
System info:
* openSUSE 13.2
* Gnome 3.14
* Java 1.7.0 (java-1_7_0-openjdk-1.7.0.71-1.1.x86_64)
* Firefox 33
* nVidia GeForce GT630 running proprietary drivers 340.58 (from the openSUSE repo, hosted by nVidia)
Other games using other libraries go straight to fullscreen correctly (Bastion, Snapshot, Aquaria, Cogs). Revenge of the Titans even thinks it is going full-screen correctly, because it logs:
Set viewport to org.lwjgl.util.Rectangle[x=0,y=0,width=1920,height=1080]
The whole screen briefly flashes, as if it tries to use the correct position, but then it ends up as in the screenshot.
This has only happened since upgrading to openSUSE 13.2, so I guess it is probably Gnome related.
Happy to provide more information if necessary.
