I mentioned the issues he opened (they are still open and not solved afaik), both of them are not solved, unless it is something that must be done on the user side. If that's the case it should be better documented, also the user should not have to resort to hacks to make his game look normal.
The image tearing is solved setting antialiasing as true for the sprites, however, what happens without antialiasing should not happen - instead of just blocky, it literally breaks the image (maybe it is caused by the same floating point problems with the jittering).
The jittering is much more complex - i'll try your suggestions, it's definitely related to frame time and pixel perfect positioning.
Thanks man!
