Problem with 2d shader

hi i have problem with any 2d shader that i add to my scene… only one that is working is motion blur… see the video… please help…

I had some weird problems with 2d filters, some of them just made my scene desapier, first try to open your game on other computer, this can be someting related with your graphic card.
after that, try to decrease the size of the whole scene, just press a and decrease it, i think that the filter maybe are crashing because of the size. And if none of this tips work try to open a new blend file and append eveything from your original scene to this new blend file.
It s hard to tell you what is the problem without see it on the file, but, give it a try maybe it works.
Good Luck
