Hi, perhaps you can give me an idea where to look for a solution:
When I switch from fullscreen to windowed mode (or vice versa), some pictures with NiftyGui are rendered in a strange way:

Resizing the window itself does not cause any problems. I use the latest stable jme with LWJGL3.
Any hints are appreciated.
Thank you.

I’m surprised that it came up at all. There is currently a known issue with restarts now working with lwjgl 3.
Thanks for the hint. Now I am even more confused. My issue was with
settings.setRenderer(AppSettings.LWJGL_OPENGL2);
When I put OPENGL32 or higher, the fullscreen stay black.
So with LWJGL_OPENGL2 it works bot not the nifty renders of the pictures, with OPENGL32 or higher the fullscreen stays black…
