well its the same in every browser, and when its compiled in EXE too, when its full screen you dont see the video shaking, but when its on window mode in the html pahe or in the xe; the player start shaking.
I FOUND THE PROBLEM:
the bug arrive only when i put: Fullscreen in browser: SCALE or LETTER BOX SCALE or CROP.
AND the only way for solving that is to do the app at the same size of the video, and is no more shake :s but if for example my videos is in 720x405 and my layout in 1280x720, the bug start again
but if i need to put others stuffs in my app, like a scrolling text in the bottom of the app or a menu etc whell its the same problem.
