LibGDX Stuttering/Jumping Movement, TiledMap, no Delta Timing

Just having experienced this problem myself, I asked google and found this thread. When moving around the map (Im not using tiled), the screen seems to get a small shunt or lag at a regular interval of about 1 second, even when I am multiplying my movement values by the delta.

I added in a for-loop to render all of my graphics 100x per frame, and the stuttering disappears completely. Very strange!

Does anyone know what is actually causing this? Something to do with the frame rate timer libgdx uses perhaps? It seems to me to be something that shouldnt really happen.

My solution to this was basically to implement graphics options, and use fullscreen by default.

When it’s run in fullscreen, the stuttering is no longer an issue, not sure how it works but it would be great to get it working in windowed mode as well.
