While I don't see expections like these anymore: `NullPointerException: Cannot invoke "com.sun.prism.RTTexture.createGraphics()" because <local9> is null` I now see this: `java.lang.NullPointerException: Cannot invoke "com.sun.prism.RTTexture.createGraphics()" because "newtex" is null` or this `java.lang.NullPointerException: Cannot invoke "com.sun.prism.Texture.assertLocked()" because "this.maskTex" is null` and the app still freezes
