Also, I'm really perplexed about a bug(?) : It runs fine from eclipse, it runs fine with command prompt java -jar Conxeline.jar, but double clicking the jar makes its frames drop to 15. If anyone might be able to help explain this, I'll be grateful. I included a .bat file that runs the java -jar Conxeline.jar for convenience, but you can type it in manually in command prompt if you prefer to avoid .bat files.
You probably got 2 gpu's.
Im facing this problem all the time, bat / exe / command line are executed with the highest gpu by default.
Java, however is excecuted with the weakest gpu.
Maybe you got the same thing going on?
