Lwjgl3Application drawing perf degrades from 1.9.10 to 1.9.11 - libgdx

Question

Hi I have a game that was using Lwjgl3Application with 1.9.10, after updating to 1.10.0 the drawing is noticeably worse on my 2014 macbook pro. You can tell the difference even when drawing a single texture. When texture are drawn, it looks like they are drawn in horizontal chunks, giving the illusion that drawing is lagging. The framerate via Gdx.graphics.getFramesPerSecond() is still ~60. On larger scenes, the weirdness in drawing is very apparent as large horizontal bands of artifacts going across the screen.
I used the project generator tool to make a scratch project to try and narrow it down, it looks like the degradation happens between 1.9.10 and 1.9.11.
In comparison, using LwjglApplication works just as well as before.
Below is the code, if running on a mac make sure to add the -XstartOnFirstThread VM arg to the desktop launcher otherwise it won't start.
public class DesktopLauncher {
public static void main (String[] arg) {
final Lwjgl3ApplicationConfiguration config = new Lwjgl3ApplicationConfiguration();
new Lwjgl3Application(new MyGdxGame(), config);
}
}
public class MyGdxGame extends ApplicationAdapter {
SpriteBatch batch;
Texture img;
int posX, posY;
#Override
public void create () {
batch = new SpriteBatch();
img = new Texture("badlogic.jpg");
}
#Override
public void render () {
Gdx.gl.glClearColor(1, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
batch.draw(img, posX, posY);
batch.end();
// make texture move around a bit
posX++;
posY++;
if (posX >= Gdx.graphics.getWidth() - img.getWidth()) {
posX = 0;
posY = 0;
}
}
#Override
public void dispose () {
batch.dispose();
img.dispose();
}
}
Thanks
