Cloth acts as if there is contant wind or an object colliding while there is none.

I worked with cloth before but this is the first time I experience a problem like this. I used two cloth objects within a canvas as within UI layer. They act as if they are theatre curtains. On 800x480 resolution the clothes work slighlty fine.(with very slight bend). Other resolutions 1280 and above, clothes go crazy. Pictures are below. Canvas render mode is screen salt textpace - camera plane distance 100.

The problem solved by itself. I did not do anything specifically. I just wanted to let you know.
