Hello!
I wanted to make a simple loading splash screen, so I used this system parameter:
System.setProperty("org.lwjgl.opengl.Window.undecorated", "true");
to have an undecorated window which displays a loading image.
However, the only way I can think of changing the window back to having a decoration, is to destroy and re-create it. The problem with this, is that destroying a display removes all the currently loaded textures, making the whole load screen pointless.
Any thoughts?
